how about a pred kills a whole bunch of aliens and marines and suddenly a marine kills him like cuts his throat or head or back it would be a twist! and that you could have like a main marine but he gets kill in the story
after the preds like put that blood symbol on the skulls they should hang them aorund the desert places like the pyramids then it will be like a warning to the rest of the marines
death you mean like to make humans come in a black hawk comes in and checks out the situiation and the aliens and preds start killin them and the marines start killing aliens and like one pred lol :p
then like there are like 5 pyramids and on top u can have three preds on each fighting hordes of aliens climbing up to get to to them and like the predators kill them and they each hold up their combistick with alien heads on each of them.
To hunt or to be huned that is the question..... But aliens will die!!!
