I thought this could be a new game added to the server so there would be maybe one or two predators to start out with. Maybe an in-game shop to buy super jumping, super speed, super strength, invisibility, etc. With in game money ofc. Humans would get guns and could get upgrades on armor and weapons. Aliens would probably be AI's. (spiders maybe with some modifications?) and I'm sure that there is some very detailed texture pack for each all of this, or one could be made . I think it is a really cool idea and would love for it to become a thing!
