Aqua

Aqua is a twin-stick arcade shooter with a steampunk theme where the player controls a naval ship from a top-down view. The protagonist is Captain Benjamin Grey, a member of the Emperean Navy fleet. Following a conflict known as the Gothean War, the Gothean adversaries return with new technology and together with Chief Engineer Polly Edison he once again has to take to the seas to stop them.

In the story-driven campaign there are eventually three different ships to command: Speedboat, Cruiser and Gunship, with different upgrades to further customize them. The gameplay is fast and the different missions include taking out batteries and an extensive amount of the game is spent on escorting ships. The left stick is used to steer into a general direction and the right stick fires, similar to Geometry Wars. There are different types of guns to collect, from nailguns to flamethrowers, torpedoes, and mines. Enemies attack from the land, sea and the air. To progress through different areas sometimes a switch needs to be shot to open locks. The ship can boost to move faster but during that time no weapons can be shot. Pick-ups appear in the water and can be collected. By killing enemies aquaflux particles can be gathered. These fill up a bar to unleash a powerful weapon that destroys most enemies on the screen.

There is a minor tactical element of the game as the player's ship can dock to hire squads that can help out. There are four types: Fighter, Sieger, Healer and Sonar. The player influences control through a menu with commands to attack, defend a specific ship or to hold ground. Multiplayer is supported through a co-op mode. There is also a head-to-head mode with checkpoint racing and arena deathmatch.
