Penumbra engine open source (non-free 32bit library dependancy)

Penumbra 1's engine now FOSS
The engine of the best proprietary horror game in existence (Penumbra Overture) has been released under GPLv3, and some parts under even more liberal licenses. The engine features a physics interaction system, which is extremely well-balanced between complexity of possible interactions and intuitive usability. A few test maps and some objects and textures were released under By-Sa-3 (in comparison: Lugaru comes with no freely-licensed assets).

The textures that come with Penumbra

There is a guide available on how to compile Penumbra and you can get some help on #penumbra or on the official forums. The biggest task is to get rid of the legacy Newton Dynamics dependency and replace it with Bullet. This 'procedure' has been applied to DungeonHack a year ago or so.

About Lugaru: there is a thread that contains some thoughts on adding free (faif free hopefully) content to it.

RubyWeekend, but also PyDay

Image
Yesterday the first RubyWeekend ended, which is a two and a half days Ruby game creation competition. The topic was "Pirates Versus Zombies!" Seven contributions were made: kiba's digital piracy parody The CopyPirate [ video ], atiaxi's tbs Port Town [ video ], satoshi's console-based footracer [ video ], jlnr's ZombieSoccarrr [ video ], ippa's Zombie Horde [ video ], jacius' Election Year: Zombies vs. Pirates! [ video ] and trejs' Caribbean Onslaught . The submitted code had to be released under an OSI -approved license and all media under one of the Creative Commons licenses (alternatively public domain for both.) The contest is being hosted on the forums of Rubygame , which is a SDL -based Ruby media library. Most submissions are based on it, some use Gosu . Ninjapix, probably PyDay #2's winner Another competition ended on Saturday: PyDay #2 - a rather fresh 24-hours Python game making contest and the smaller brother of Ludum Dare ,...

Open Source Game Engines

ScummVM FIFE OpenTTD Today is a game engine special on Free Gamer. These are the projects that take your favourite [old school] titles and provide not only a native port but also fix all the nasties that had you saving and loading or even resetting your PC in the past. I remember the days of autoexec.bat and making every byte of that 640k count. Well these won't give you that fun but at least you get to play your old games! Let's start with the exciting FIFE: Flexible Isometric Fallout-like Engine . Started as an attempt to make a Fallout engine, it is becoming more ambitious and there are even rumours of a FIFE-based game in development. It should be able to run fan-made Fallout mods like the aptly named Fan Made Fallout . I have a pet favourite among RPG engines - GemRB . (I respect the steady progress on a difficult project.) This Infinity Engine emulator aims to be able to run the Baldur's Gate titles and even improve the experience they offer. The development...

Anticube 2 - a game within a game

Image
So, as I sometimes peruse various forums, the occasional gem pops up. This is one of the best hidden gems in Open Source gaming. Anticube 2 is a map for Tesseract / Cube 2 that is inspired by the game Antichamber and NaissanceE . If you are unfamiliar with those, that means it is an abstract FPS puzzle game where things are not quite what they seem. Or, as the creator Lord Kv probably better explains: Anticube 2 is a puzzle map for Tesseract. You'll find yourself in an interactive, dynamic, non-euclidean world. Supported by 5000+ lines of Cubescript and GLSL code, this map will do things no other Cube 2 / Tesseract map has ever done before. Here is the trailer: There is also a gallery of screenshots for you to check out. I won't include them here because, to be honest, the screenshots won't mean much for this kind of game. I'm calling it a game, even though it is just a map for a game. You can tell it is worth checking out because of the reactions it elicits from...
