An exceptional round as XO. The following happened:
A prankster with IFF caused an actual shooting during briefing
The Xeno hive was accidentally discovered because marines were so disorganized they actually encircled the aliens
The xenos tunneled out, leading to a 1 1/2 hour addition to the round
an SO opened fire in CIC during a big fight, leading to the marines getting almost wiped while I domed the SO.
The SO was brought for execution, only for the messtech to shoot the firing squad, resulting in the CMP, Myself, and an MP all shooting each other and being ahealed multiple times
The CO woke up and we deployed stims and finally won.
