Fling your monsters into battle! This building is required if you wish to attack another player. Use the Map Room to find and target enemy yards.
The Flinger is one of the few buildings required to attack other player's bases. the way the Flinger works is by placing monsters you have in your Housing into the bucket, and then flinging them away to an enemy base. Upgrading the Flinger will allow you to send more monsters at a time. It will also let your attack more people(in Map Room Level 1), or it will let you send your monsters farther away from your base(in Map Room Level 2).
