Two healers.
One main offense. The two healers both heal the other healer and the main offense. Yay, invincible... at least there are some weapons that kill faster than the healers heal.
A badge in a multiplayer game? Kind of hard, except maybe "Get 100 points" "Get 200 points" "Get 1000 points" and "Get 10000 points"...
As for the game, w00t pie yes...
4.8/5, 5/5.
