and this maybe off topic and you can move and delete this or whatever, but I was playing and I was thinking that this would be awesome for Left for dead 2! I mean the zombies could be gaunts with the special zombies being the more evolved tyranids like the tank could be the carnifex and the charger could be like a hive Tyrant and the smoker could be Lictor ect.

The survivors of course would be a space marine veteran combat squad fighting its way to kill the tyranid infestation on the world!

Of course different maps could be different worlds with different threats like maybe an ork or necron map though I doubt that would work like tyranids

Just an idea to put out there that maybe might spread into something and I hope it doesn't offend any of the mod staff here as its still a great mod that I think is an awesome idea that can work elsewhere. Keep up the work
