I tried to have 15 seconds to spare, but could only get 10.5 seconds or so. The last two minutes is easier than the area before. Both carpet bombings and jets at the same time, with bomb squads and mutants, and finally all those military vehicles.
I've played and beaten all five games and enjoyed them. Nevertheless, I've seen some racist/sexist stereotypes. Shane is black and low intelligence, reinforcing a racist stereotype about Africans. The game also suffers from the Smurfette syndrome, in that Anne is the only significant female character with the exception of scout in episode 4 Berger. Still, the game assumes a straight male as the main character, with Sage, Duffy, and Anne as the other three, 25% female 75% male reinforcing the sexist smuffette syndrome.
