COR Entertainment has announced the latest release of their open source first-person shooter, Alien Arena 2008:
Version 7.20 features a host of improvements, optimizations, and new features such as the implementation of per-pixel GLSL effects including parallax, normal and specular mapping/highliting, occulusion culling of entities, shader performance boosts, new and improved weapon/event effects, and much more. The end result is a game that not only looks great, but also runs considerably faster than previous releases.
On the gameplay aspect, a brand new reward system has been implemented, allowing players to choose from three powerups when reaching a certain achievement total. Weapons have received further balancing, powerup effects made more smooth, and various bugs have been squashed. Several brand new levels have been added, as well as player skins that improve visibility and an HUD based weapon inventory.
