Since we already have your biggest fuckups as xeno, might aswell have the most awesome moment.
Mine is definitely the round of Prison where I was the Queen, all of it.
The round was going pretty well, but our numbers were whittled down quite heavily, and during LZ1 FOB siege, we had less than 10 xenos.
The marines try to push, but we hold.
They end up retreating to come back, while I'm ovi'd up in the security dorms, that small room next to tcomms corridor.
A warrior and a drone end up grabbing and infecting so many people that the admins themselves come down and rename them Abductor and Infector, respectively.
It was beautiful to watch, marines getting grabbed one by one, each of them added as capture to our makeshift hive.
All of the time, we were right there, but the marines failed to take us out, despite still having quite good numbers.
In the end, we grabbed enough captures, got enough xenos, and boarded the Almayer. I think we won.
