Character mistake: During radio conversations, the BSAA operatives keep changing the way they refer to each other. Sometimes, they use real names, other times they use codenames. They should stick with one method, it doesn't make sense otherwise.
Other mistake: If the player tries to leave the virus tank area in the laboratory, Chris will comment "Jill, where are you going?" but the caption reads "Where are you going, Jill?"
