Alien Arena is an open sourced game that combines a sci-fi atmosphere with the tournament style deathmatch of Q3A and UT2k4. Major graphical features such as GLSL per-pixel lighting, ragdoll physics, light blooms, real time lights and shadows, textured particles, shaders, and reflective water, create a colorful and immersive deathmatch atmosphere. The game also includes mutators, adjustable effects, bot skill settings, and fully configurable deathmatch, team deathmatch, CTF, All Out Assault, Team Core Assault, Cattle Prod, and Deathball games. The game features original artwork, with a dark, sinister atmosphere combined with an off-the-wall campiness, and trippy, techno type music. There are currently over 60 maps, loaded with weapons(each having an alternate firing mode) and powerups. Alien Arena has fast, smooth gameplay, & players can play online against one another or against the bots. Please post all support issues in the forums for the game.
For Alien Arena 2012, we are ramping up some things with the renderer. One of the new features is that we added subsurface light scattering to our shaders. Subsurface light scattering is what happens when light enters a translucent material, such as skin, or in this case, an exposed brain :) The light rays enter the material, bounce around, creating a glowing effect around the rim. Think of how it looks when you hold a flashlight up behind your hand, to illustrate. We are able to approxiamate the effect in GLSL as demonstrated.
