Best Open Source Top-Down Space Shooter : Super Space Invader

Lasers, rockets, shields, health regeneration, pixels. You know. The good stuff. Just nicely packaged with levels of just the right duration and hardness, persistent upgrades, shaders, reverb...

Two buttons are enough to play, since that was one of the themes of Ludum Dare #34, in which the game came #74 among 1638 jam entries.

Super Space Invader Review

Supser Space Invader was made with LÖVE (v0.9) and thus runs on Linux, OS X, Windows.

Space Station 13 remake liberated!

Many of us know Space Station 13 as "that awesome game I never played". Along with games like Dorf Fortress it stands as one of the pinnacles of the gameplay philosophy of fun through massive amounts of diversity. Originally developed in one of the most broken and unupdated platforms ever imaginable, BYOND, fans of the game have been trying to develop a standalone remake of the game for a while.

After a long period of development, the team of Robust Games, in charge of the project, decided to liberate the whole thing and turn to open development. This means all of the code is now GPLv3 and all of the art assets are now CC-BY-SA, effectively making the game 100% free-as-in-free-domes. 

So what are you waiting for? Get to developin'!

EDIT: Apparently only the placeholder sprites (not the fancy ones in the screenshot) have been released under CC-BY-SA. The game should still be 100% playable with these, though.

Godot Winter Game Jam

Godot winter icon

A game dev jam to create a winter-themed open source game was community-initiated at the Godot forums. The (vote-determined) winner will get a budget of USD 50 to have donated to an open source project of their choice.

What is Godot?

Godot editor

Godot is a game engine. No wait, it's actually a game development IDE with its own Lua-based scripting language.

As far as I can tell, it's a promising project that is a bit buggy, especially when it comes to mobile exports. It has some UI flaws (subjectivity warning) but still, open source Godot is more appealing than proprietary Unity 3D.

If you want to try making a game in Godot, I recommend this official tutorial as a starting point. Good luck & great success to you!

What else?

Another way to support Godot: "like" it as a Unity 3D alternative on alternativeTo.

Strife: Veteran Edition

Just in case you can stand having Steam DRM installed in your system, I recommend taking a look at Strife: Veteran Edition. Strife is a Shooter/RPG based on the Doom Engine and dating back to 1996. The developers for this new remake had the wits and sensibility to use the Chocolate Doom engine as the main code base, which is, of course 100% licensed under the GPL. With so many top quality Free Software engine remakes around here, it really astounds me why so few developers choose to use them on modern HD remakes and ports (I'm looking at YOU, upcoming remake of Heroes of Might and Magic III not using VCMI).

As mentioned, so far the game is available exclusively on Steam, but I'm pretty sure a DRM-free GOG version will eventually follow, as it usually does.

Citadel makes big promises

There's a new big remake effort a-brewing in the Free Software world, this time for prominent shooter/RPG, System Shock. under the shape of project Citadel. According to project description, the goal is to recreate the original game using the widely known GPLed platform Darkplaces Engine, upgrading the game's graphics to full 3D but keeping game aesthetics close to the origianl game. Added modding capabilities and cooperative multiplayer will also be a part of the project. 

Details, however, are somewhat scarce, so far, as development is happening behind closed doors, and creator Josiah Jack just announced the existence of the project itself after months of programming in secret. While the code will certainly be all GPL or GPL-compatible due to Darkplaces licensing requirements, the game appears to rely on original proprietary assets, as well as using its own whose license nature is yet to be disclosed.

With a release date planned for the the 23rd of December, System Shock's CD release anniversary, I guess we'll have to wait and see if this project will deliver.

Duck Marines, FOSS remake of ChuChu Rocket

Thanks to Tangram Games for pointing out to us that they just released version 1.0 of their local multiplayer game Duck Marines.

They describe it as:

Duck Marines is a cross-platform free software PC remake of Sonic Team’s ChuChu Rocket.
Duck Marines attempts to recreate the magic from the local multiplayer of ChuChu Rocket while adding new elements like mini games, a level editor, colorful pixel art and more.

But see for yourself:



For those not familiar with the original on the Dreamcast here is a small description of the gameplay:

The goal of the game is to get as many ducks into the submarine of your color. Gray ducks give you one point, gold ducks give multiple points and pink ducks will trigger an event or mini game.
Guide the ducks towards your submarine by placing arrows on the ground. When walking over an arrow ducks will instead walk in the direction the arrow is pointing.
Beware of the blue predators. Predators love to eat ducks and will kill a large number of your ducks if they reach your submarine. Try instead to guide the predators to the other players’ submarines using your arrows.

Source-code (zlib) can be found here, assets are licensed under the CC-by-NC-SA/ND. Build with the great Lua 2D game framework LÖVE by the way.

OpenRA also has a new release

OpenRA is a Free Software recreation of the famed Command & Conquer engine, and it aims to support and enhance all Westwood games originally built upon it, namely Tiberian Dawn, Red Alert, and Dune 2000. However, unlike most engine remakes, OpenRA isn't a simple 1:1 recreation with a little streamlining here and there, as the project also aims to optimize and rebalance the gameplay for purposes of online multiplayer. The project has recently released the latest stable version, fixing a lot of bugs and adding plenty of new features, as seen on the following release trailer:

Interestingly enough, in order to play all the games supported by OpenRA, you are not forced to own an original copy of any, given that all three ones were released gratis a few years ago. Though the package comes without any of this data, it immediately invites the player to download it from the project's own repositories, thus making all the games readily available to play.

The campaign mode is still not fully supported by OpenRA, with only some missions available for playing and no cinematics support at all, but we can only hope this will change in the future. In the meantime, you're free to enjoy all the supported games in skirmish mode, or play online against friends. So here's to the OpenRA team, and keep up the good work.

OpenXcom hits 1.0

We have previously mentioned OpenXcom on several occasions before, but now the massive UFO: Enemy Unknown engine reimplementation project finally hit the long-awaited 1.0 mark, and they decided to celebrate by releasing this lovely trailer that sums up quite well the insane amount of detail and improvement put into the project over the course of 4 years. I'll let it do justice by itself, but not without thanking all the contributors for raising one of the most acclaimed DOS-era strategy classics from the stagnating swamps of buggy unsupported legacy releases and platform incompatibility.

On a final note, the engine is, of course, free-as-in-freedom, though it relies on original game data of proprietary nature. You can download OpenXcom here, and buy an affordable digital copy of the original game on Steam, or somewhere around the web.

Code License: GPLv3

FlightGear 3.0 and Bombable add-on

This week saw finally saw the official release of version 3.0 of FlightGear.

Notable changes:

Highlights in this release include integration of the FGCom voice communications client within the simulator, improved terrain rendering, faster scenery loading, and improved usability. This release also coincides with the release of FlightGear World Scenery 2.0 – massively improved scenery data covering the entirety of the planet and incorporating OpenStreetMap roads and detailed terrain information from a variety of sources.

Also interesting is the "Bombable" add-on, which adds combat mechanics:

December RTS updates

Merry Christmas from FreeGamer!

As a nice present from the 0 A.D. team, the new Alpha 15 Osiris was released today:



Lots of great new features and especially multiplayer games should be now much easier to do with hosting improvements and a lobby for browsing available games.

Another open-source RTS engine (using Mono/C# though) has also released a new version: OpenRA. Currently it is still geared toward running an assortment of older Command & Conquer based games, so you need to own these for the data. But this release adds lua scripting for the creation of custom missions, so maybe someone will come up with a libre game to run on this engine.

Last but not least, a new version of Warzone2100 was released about a week ago. This one actually includes some higher resolution textures, which is hopefully the first step to officially integrate all the awesome new art assets from the art revolution project.
Speaking of WZ mods: There is also an interesting new tower-defense mod currently being developed.

Zelda can now be free as in freedom

Not only from the clutches of Ganondorf, but also from the dominion of proprietary software. All thanks to the magnificent Solarus Engine, a GPLed, SDL-based, 2D action RPG engine. This amazing project aims to provide a stable and easily customizable platform for users to create their own Zelda-like games, and so far, I must say, I am darn impressed by what I've seen. The engine already has two incredible launching titles, named The Legend of Zelda: Mystery of Solarus DX, and a parody of the former, Mystery of Solarus XD. Both are true love letters to the classic SNES RPG, The Legend of Zelda: A Link to the Past, and amazing and enjoyable games on their own.

Mystery of Solarus DX

But hark, the mere words of a mortal make no justice to the grandiosity of this undertaking. Sheathe thy sword, get thy green cap and ready yourself to adventure! You can start by marching straight to the Solarus download section, or, if your intentions are more creative, you can check the various sources here, and the quest editor here.

GSoC 2013 pushes SuperTuxKart forward!

If you follow our planet, this is no news, but the recent advances in graphics, networking a other stuff from SuperTuxKart are quite nice. This is basically a result of them being accepted to this years Google Summer of Code.

Not showing most of the new features yet is this nice video featuring the mascot of OpenGameArt.org as a new player character:



But their blog has many interesting technical details (and other screenshots + videos) to show off the new features.

So if you like to also contribute, or just want to praise the great work, have a look at their FreeGamer hosted forums :)

Cataclysm: Dark Days Ahead, funded!

The self described open-source rogue-like survivalcraft / driving game in a sci-fi zombie apocalypse has successfully reached its goal on Kickstarter, and one of the developers will now be able to work on it full-time for a few months to implement for example a back-end for proper graphics.

But see and hear about it yourself:


The first stretch-goal is close too, with 12 days remaining to pledge money towards this cool project.

Less rosy does it look for the previously featured Data Dealer project. With only 48 hours to go, but still about 10k missing it will be a close finish if at all. They got some remarkable press lately though and jumped up about 10k in the last days, so it is still possible. So if you haven't done it yet, pledge here.

Xonotic 0.7 released

After an agonizingly long wait, I am happy to report that a new official release of the premier FOSS arena FPS Xonotic is available to the masses.

Here is a nice (but slightly older) game-play video for those not having played Xonotic yet:



Changes are quite extensive compared to the last official release... most notably an extensive update the the CTF mode, some neat additional features for competitive gaming and an assortment of great new maps.

New maps in Xonotic 0.7

On the technical side of things, the engine DarkPlaces got quite a few performance improvements (mainly due to the fact that the creator now works at Valve software and thus has direct access to Nvidia's and AMD's graphics hardware divisions) and that an all new script compiler is now in use. That it runs on SDL 2.0 might also increase it's usability a lot for some.
There are also finally an animation bending feature for the player-models and creation of new characters has never been easier now that the iqm format is used.

You can comment on this release over at the Xonotic forum release announcement thread (or of course here in our comment section).

Also check out these two still under heavy development mods for xonotic:

• Overkill is a mod that attempts to combine the best of minsta gameplay and TDM/CTF. It also has some nice vector shaded new weapons and player models.
• DotC is an DOTA like but in 1st person view type of mod.

Last but not least, the awesome all new level editor for quake based games, Trenchbroom is making great advances and should soon allow easy mapping for Xonotic out of the box.

P.S.: If you have a really fast Android device, you can also try to run Xonotic on it via this newly fixed DarkPlaces port. Just don't expect to be able to compete online with touchscreen input :p

Hedgewars 0.9.19 released

Everyone's favorite clone of worm-warfare, Hedgewars recently got a rather big new release as one of the developers pointed out to us by email.

One of the new level themes for Hedgewars 0.9.19

The changes are quite extensive, so instead of failing to summarize them here, check out the above linked quite extensive original release announcement.

You can also have a look at this fan-made trailer if you enjoy cheezy stuff ;)

2x0ng: Procedural Puzzle-Action Adventure

Retro and art-game fans will love this.

2x0ng is a challenging action/puzzle game with procedurally generated levels. It is pronounced "TWO-zong", and is the sequel to David O'Toole's 2009 PC puzzler Xong.

2x0ng framebuffer examples

At its core, this game is a mashup. 2x0ng's design is a nonlinear combination of several different late 70s/early 80s home video games, combining related aspects of each into something new. In 2x0ng, you move a guy around the screen and shoot at enemies in all directions, as in Berzerk. The ball you throw ricochets and comes back to you, like in Tron Deadly Discs. You break colored bricks with the ball, like in Breakout. You transfer colors from one place to another in order to complete the level, similar to Revenge Of The Beefsteak Tomatoes. 

To reach the next level, you must successively unlock new areas by opening color-coded gates in the correct order. The levels are procedurally generated, so the game experience is different each time. Later levels are much larger than the screen, and feature substantially more moving/colliding objects than would have been possible in a real home video game from that era.

Downloads:

• 2x0ng 1.0rc1 for Linux
• 2x0ng 1.0rc1 for Mac OSX
• 2x0ng 1.0rc1 for Windows (32-bit) 
• 2x0ng 1.0rc1c for Windows (64-bit)

Red Eclipse 1.4 and a missed birthday

Good news is that the long awaited Red Eclipse version 1.4 was released yesterday.
Read the announcement (with full change-log) here. Besides general polish the most notable features are:

• Vanity items and improved colours: dress up and frag with style.
• Visible legs in first person: know where you are kicking and parkouring.
• New and revamped maps: bringing you even more variety.
• Better viewing: level flythroughs, improved third and first person cameras.
• Better menus and other HUD elements: easier to see and read at a glance.
• New weapon: Mines add a new dimension to the existing gameplay.
• New mode: attack and defend in Gauntlet, competing for the most laps.
• Automatic demo recording: for those times you just have to watch it again.
• User Accounts: donate or contribute, and wear the in-game supporter badge.
• Improved weapon balance and gameplay rules, bugs fixed, and much more.

Especially the visible legs in 1st person view add to the parcour movements and overall the game feels much more "complete" now. Here are some impressions of a bot-match I had earlier on:

The bad news is  that we missed Xonotic's third birthday, but you can still congratulate here (where you can also read about some pretty cool updates to the game). To celebrate it, kojin made a nice frag movie:


Enjoy!

Shunned Survivor: MMORTS Tower Defense

Defending your outpost in Shunned Survivor

Shunned Survivor Commentary Video

Shunned Survivor is one of the entries for PyWeek #15 September 2012 "One Way Trip".

In the genre mix between MMORTS, city building, economy simulation and tower defense game, you control an exiled human, with the apparent goal to get back to earth.

The interaction with other players is quite indirect. You can attack other player's bases and win the "data" resource this way, which you need to perform "research" actions. However, defeating a base does not change it, you simply get the reward and can attack again.

Shunned Survivor Server map

While researching, however, you need to perform in a tower defense minigame, during which your defensive towers can be destroyed. If you succeed, the research was successful. If not, you have to enforce your defenses and try again.

Even though quite a bit of the gameplay time is spent on waiting for resources to be generated by the various resource gathering buildings, I find this game very entertaining and highly recommend you to give it a try.
