I finaly got it to playable form and objectives aren't too hard like they were on Beta 1 (private version for clan).
screens:





Aliens defend and Humans are attacking and try to complete objectives.
Crappy objective map:

1. Have two players on sides to press the buttons then 1 of them hurry to press middle one in order to open metal bar gate.
2. Solve button puzzle to open path in sewer filled with poisonus gas.
3. Press the button to open gate on sufurance
4. Jump consle button to lower the shield on gate lock and have someone unlock the gate before shield blocks it again.
5. Destroy overmind to reach the alien egg life support system
6. Kill all alive aliens (I know that flaw of the map lets them camp in the vents)
Aditional map info:
Aliens can't build.
Jetpack is disabled.
Humans have 200 bp
