I'd love to see a predator movie with only predator characters, and maybe even no dialogue, even no dialogue, leave it to a very visually talented director, that can tell a story without dialogue, I think it could work.
but I also agree that the 'code' is much more like common trends hunters use, like the general consensus is that predators typically don't kill prey that wouldn't be worth it
because if this was a code that should be followed by all, who the hell is watching these solo hunters when they are off of hunts on other planets, we see the mother ship in P1 simply drop the predator off and fly away.
but I'm sure wolf wouldn't care about following any typical honor rules on a special job like this
and if that supposed face description from the one website is true, we will definately see that he is 'the most leet of the leet' of predators, having half his face burned with acid, and missing one eye, its apparent he has been through some serious combat.
