[IDEA] Game Mode - Slaughter

I think it would be cool if you had a game mode where all players are on the same team.  Then waves of creeps are sent against you and you have to kill them.  You would have limited resources and it would be in part cooperative.  You could add a competive element to the mode by keeping a scoreboard of creep kills.  I just find that killing massive ammounts of creeps is entertaining so a game mode centered around it would be cool.
