It literally steals from PopCap's Heavy Weapon in that it features the same weapon set almost in its entirety, and they even look the same on screen when used. Include Geometry Wars 360 degree shooting in a horizontal scrolling title and you have UFO's Underwater Attack.
Copy or not, Underwater Attack is still enjoyable. It takes some time to get started and up to speed. In fact, the first few levels before your ship is powered up could be enough to turn off those who are less patient. They're terrible, with no intensity, awful weapons, and a ship that moves are 10% of the speed of the enemy."
