Involving combat with water guns, Hudson has described the family friendly game as a "first-person soaker",[3] which holds up Hudson's core design philosophy that prohibits explicit violence between people playing a game.

[4] Along with replacing firearms with water guns of several types (such as water firing machine guns, sniper rifles and rocket launchers), the game also replaces grenades with water balloons, armor with raincoats, and health bars with wet T-shirts, with health regenerated as the shirt dries in the sun or by the player picking up a towel.

The water guns are refilled via drinking fountains situated around each level, with the game featuring 8 maps set amongst nature parks, beaches, playgrounds and a Venetian city.

Six multiplayer modes are featured including Battle Royale (survival), Deathmatch, Treasure Chest (capture the flag), a team-based Assault mode and Point Rally (race).

The game also features a 38 mission long single player campaign, a spectator mode and bots to play against.
