Square Enix describes the game.
In FOAMSTARS, foam is the ultimate resource. It can be used in multiple ways: To create slippery surfaces that players can use to surf around the arena at high speed; to build terrain, helping players defend from enemy attacks or creating high vantage points to take out opponents; and finally, to foam up the opposition and win the match.
