How do you beat alien level 11 on raze 2

the level is in the map, 'facility'. make a quick run for the invincibility (purple barrier)
and any weapons in the way. once there, shoot everyone out BEFORE grabbing the flag. abilities will not work after you grab the flag. if you're on the bottom, use the jump pad at the right. you have to have good timing, because you need the flag as soon as possible. don't worry about guards. everyone goes for the flag.
