0 A.D., the open-source game from Wildfire Games that has long been under development, has seen its 11th alpha release on Friday. This cross-platform RTS now improves the realism by introducing several post-processing effects and mapping enhancements by implementing OpenGL GL Shading Language (GLSL) support finally within the game. The GLSL support is currently disabled by default but will be enabled in a future release, with support for ambient occlusion, normal mapping, parallax mapping, specularity, and tree swaying with winds. There's also custom terrain alpha-maps, fancy grass material, and tri-planar mapping for terrain.
0 A.D. Alpha 11 also features new art assets, new sound tracks, user-interface improvements, and game-play improvements. The game-play improvements for this Linux, Windows, and Mac OS X game includes new Celtic factions, a new AI script, gates, a new sound system, and shared LOS among allies.
More information on 0 A.D. Alpha 11 is available from the project's announcement.
