Cooperative Survival Mission (Unnamed - Alpha version)001d

Demo map under development. Unlock units for purchase by having the right secret combinations of enemies on field. When you start building the expensive helicopter (it's a flying battlefortress), the timer will start. At the end of the timer, a reasonably large force attacks. ===> ENEMY AI YURI AND START #8. PLAYERS: DON'T PLAY AS YURI. IMPORTANT: IF the game crashes or freezes or anything like that, please type in the lobby after the game, all the recent things you noticed. This will help me pin-point possible bugs and PREVENT THEM in future maps!
