Hi this is my small idea for the game:
Predator should grab enemy(a.i. and player) and use them as shield and/or throw them like in the movies.
My second idea is to add a hub system like in dragon ball fighter Z. Players can walk and talk together(military base for humans and alien space ship for predators). They can chose party on a screen or something and wait for battle…
Matchmaking system must let group choose to play commando and/or predator to fitgh friends.
