Here’s another free and open source game engine to the steadily growing library on Linux. Tesseract is an open source First Person Shooter derived from the Cube 2: Sauerbraten engine.
Tesseract is a first-person shooter game focused on instagib deathmatch and capture-the-flag gameplay as well as cooperative in-game map editing. The game engine is derived from the Cube 2: Sauerbraten with specific unique enhancements that makes this game stand apart as a spate game engine altogether. The engine is open-sourced so it has the potential to be enhanced further. The game engine, although derived from the Cube 2, comes with upgraded with quite a few modern rendering techniques. The new rendering features include fully dynamic omnidirectional shadows, global illumination, HDR lighting, deferred shading, morphological/temporal/multisample anti-aliasing, and much more.
From the looks of the demo video, the game looks really pretty, something that would otherwise have definitely been paid. The starting map shown in the demo looks especially well-suited for an intense multiplayer session. In addition, the game’s in game editing capabilities needs special mention. You don’t need to be in a separate module to design your level and then have to load it up and test it. You can modify the level while inside the game, switching seamlessly between editing mode and gaming mode.
To make it even more interesting, you can even design the levels cooperatively, thus creating complex maps with your friends in no time. The character models and the guns are especially nice looking and they can be even further upgraded to be more realistic thanks to the engine being open source. As for the performance, the game seems to be even more efficient than Unity. According to user reports, the optimizations of this engines, makes the game run real smooth than other standard shooters. Anyways, this is just another nice addition to the steady library of Linux games, with the advantage of having a wonderful and innovative editor. The game is available from download from its parent size for Linux. The game weighs in about 237MB too, which is quite small given the things it allows you to do!
