For people and teams developing mods and games with Valve's Source engine.
This version has destroyable walls (the castles will be almost all destroyable), the rain is too much already got feedback from gamebanana, and well, not much to say now... BETA4 will be more optimized because it will feature aeraportals and occluders... so the fps will be a little bit more steady.
THE SCREENSHOT IS FROM THE EARLY BETA, THIS version doesn't have grass and has palm trees instead
