Zombie Rift Gamemode
I love League and I love Zombies from COD, so why not have both in one epic game mode?
Just think, its 5 champions against endless waves of zombies that gain in numbers, get stronger, faster, and smarter with each wave. There could be grave stones or something everywhere on the summoners rift map and zombies slowly climb out of them just like how they climb in through the walls in the normal COD zombies game. goal is too see how long you last.
