Right then, I think I’ve found a bug, but I don’t know if it’ll repeat. I’ll repost below if it doesn’t reoccur when I try it again.
Defend the hotel: I’ve gone through 24 waves of enemies now, and I’m not sure that can be right. Each time the last machine or two disappeared (though not the last time) and I was back to talking to the girl on wheels. Same conversation three times and then the waves started again. It can’t be time-limited, can it? You have to destroy the last wave in a set time or you’ve failed and have to do it again? That’s not like you lot, and quite rightly, so I think it’s a bug.
I’ll go back and check when I’ve recovered (wow I was pee’d off after the 24th wave, not to say wicked short on ammo).
I’m on PC, just below minimum spec (according to @Voodoo, who knows about these things).
P.S. I never saw a Tank, just Hunters…
