it would be cool if you could unlock that predator/alien crossbreed as a class. it would be really strong and fast but have downsides like it couldnt climb trees because of its sheer size but can jump far but have less stamania. stronger but slower attacks and it would be feared above all, he could run somewhat fast but can have its legs shot alot and crippled and when its crippled it can not jump or something like that it would be so fun to have something like that but it might be a while till we get it.
its just a thought. :)
