I've played it once as alien.
The rines held door room, lots of turrets and rines, but we managed to get a few fades past. By dividing their attention the door room fell into our hands, they lost their RTs and the "alien siege" began. Once we were fighting in marinestart it was a pice of cake, it's really designed for blinking :P

Even tho we won, it seems like it's quite easy for riens to hold the door rooms and the rooms beyond. I'm sooo looking forward to comm on this map
the map looks nice unsicht, gotta play it some more to give you real feedback
