Nice game,but i have a idea for next update.

Can you add like a zombie mode where you can be a zombie for example 4 players be zombies and 4 players be normal players and the zombies need to kill the other players. And give the zombies some buffs and make the zombies level up to get more skill and do more damage.And this is a AWESOME game you have.
