From Wikipedia: Adventure Time: Battle Party is a browser-based Unity Web Player Multiplayer online battle arena game made by Cartoon Network. Like other Multiplayer online battle arena games such as League of Legends and Dota 2 the player and team take down the other team's base. Unlike other MOBAs, players cannot level up their skill or buy items. Instead players customize their characters via pre-made"backpacks" that give different stat bonuses. Matches can either be PVP or against AI. Matches end either when one team's base is destroyed or when time runs out. Upon time-out, the team with the most points wins.
