Ugh, i rewatched the damned thing too, and i found myself ignoring the entire story the moment those gay-ass renmants appeared and Loz, the most manly out of the three, started crying and whimpering......

And yes, nothing is explained in the movie, like, where the hell did they got those bikes, or where did they get the money at all????
I can understand that they used "magic black goo" to make tight clothes appear on their bodies, when the Turks found them in the crater, but seriously.....the bikes and guns they own still confuse me XD
