Yeah, I think you have to lock into the beacon with the big one first.
Oh, and I "won" as alium for the first time! I was BOB JAMES, but I was dead by teleporter. And then I was an alien larva in atmospherics. So I evolved, but I accidently picked sentinel instead of drone, so BROKEN DREAMS D: D:
But I crawled to xenobiology, but found myself unable to leave xenobiology trough the vent, because crawl trough vent decided to break. So I started planting weeds, and murdered some guy in a firefighter suit messing in toxins for god knows what reason. After that I went up to the hallway, planted some weed in medbay, and noticed the two remaining survivors: the captain and a guy in a security hardsuit. They cleverly dodged me and fled to the shuttle. I managed to neurotoxin the guy in the security hardsuit in the escape hallway, but then I noticed the shuttle would leave in 7 seconds, so I scrambled to the shuttle with the captain on it. I made it. The captain had buckled in, I planted a weed and then decided to spit neurotoxin at him. Then I bludgeoned him to death for one minute. VICTORY!
In short, weed and acid saved me.
Also.
YOU KILLED BOB JAMES. BE ASHAMED!
E: I just realized one other thing that saved my life. I built a turret frame in the middle of medbay as BOB JAMES, wich the CMO pushed out. The guy in the security hardsuit accidently walked against it in the middle of the hallway, slowing him down enough to neurotoxin him. Else I would have been fucked. Aaaaw yis. Thank you, BOB JAMES!
