This is an add-on to the 4 player co-op idea I had, instead of it being 4 player, it should be a 12 player co-op, because then you could have 4 marines, and 8 are the aliens, when you are an alien, you can choose your type of alien, but when you die,(as the alien) you wait 2 turns and then you get to choose again, when you are a marine, when your health is 0 you should have 2-4 turns to be revived, you cant attack when you need to be revived, but the aliens can attack you once when you are down and there is a 60% chance of getting hit when you are down, but when an alien is not attacking you, you cant lose hp, when you die you become an alien.
plus this if you think this should be in the game.
this game is awesome, but it should have a map maker where you can create your own map, and you can share it online with a 4 player co-op mode. plus this if you think this is good.
