We finished the first and second levels, they were both prologues and are now complete with character AIs and stuff, they won't follow you on this level, but they do react.
We're now passing to level 3 and 4 where the player visits aparently deserted space colonies with his squad... we hope to release a beta or demo soon including 3 random levels where you're gonna be able to experience Squad AI in battle and all the weapons you can have during the game, in the demo we won't include any official enemies that we'll include in the final game, instead were gonna make enemy squad try to take you down... hopefully this will be out in 2 weeks.
