It's been over six long months of dedicated, at times daunting, and ultimately triumphant work...and COR Entertainment at last announces the release of Alien Arena 2009!
You've seen the screenshots, the videos, now it is time to face the alien invasion head on, armed to the hilt with disruptors, beamguns, and vaporizors. The amount of improvements to the game engine are staggering. The game comes alive with the full implementation of GLSL per-pixel lighting on all surfaces, OpenAL audio system, and new gameplay features. Optimization was as always, another aspect that we've addressed. No longer does one have to be leary of cranking the settings up, the game plays remarkably faster with the switch to GLSL for per-pixel operations. Alien Arena has transformed into a lean, clean, fragging machine, with stunning visual effects that are usually reserved for commercial titles. This isn't your daddy's Alien Arena - it's not even last year's model, with a host of new and improved maps, sounds and music.
Some of the new features in this release:
* GLSL per-pixel lighting on all surfaces.
* OpenAL 1.1
* Ogg-Vorbis support.
* GLSL post process framebuffer effects.
* New scoreboards.
* New HUD.
* Stereo music files.
* Seven new maps and two new player characters.
* Light volumes.
* Voice taunt system.
* Doppler sound effects.
