Exobius0 is a 2D shoot-em-up game with 13 levels featuring multidirectional scrolling.
It's worth noting that the download size may seem quite large, however, this is due to the game's high-quality graphics and complex gameplay. Unlike other open source "games", Exobius 0 is a fully-featured game, not just an engine.
The graphics within the game were created using Blender, and then were masterfully crafted together onto the background bitmaps using Gimp. Overall, the user experience is out of this world, and I would highly recommend this game to anyone looking for a high-quality and engaging shoot-em-up game.
