Add a dota style pvp, two blood fountains either side of spawn points.

Ingame exp for kills that total towards upgrading main base to spawn better minions, attack each others base using minions.

Aim of the game is to swarm the opponents base with minons to destroy the base, player kills earn exp towards upgrading base, spawn time takes longer the longer the game goes. Nah mean!!!

And prevent spawn camping tower of doom or somethin.
