A few goofs/questions
1. Amber & Napolean's rifles get stolen, but later they have some. Did they take them off the guys that died? Mickey would have had his with him when he was dragged under, Spitter's & Sarge's would have gone down the cliff with them, but by the time they found the guy that shot himself they all had rifles.
2. At the end the heat sensor shows the 3 survivors, but surely it would be able to detect heat from inside the caves as well. What about the other soldiers and mutants that died? Especially the one that raped Missy, he was only seconds dead at that time so he wouldn't have lost much heat at all then.
3. What does Napolean say to Crank in Spanish that upsets him? I know Crank called his mother a whore, and I think Napolean said "idiota", so was he calling Crank stupid? I don't speak spanish, but what Crank said in Spanish was in the subtitles and what Napolean said wasn't.
4. Were Micky and Amber together? One guy says they'd be having sex in a tent, she seemed to have been flirting with him when he put his finger up at Napolean (although that might have been Stump, I couldn't tell the difference between the two) and she seemed the most upset when they found Micky's body.
