Aquattack is an action game with four levels, each with its own unique challenges. In level one and two, you'll be in a motor boat, navigating left to right while avoiding enemy opposition. Some enemies are shootable, while others are out of reach. You'll need to collect fuel by collecting refreshments dropped by allied planes. Level three is similar, but this time you're using a hang glider, with different enemies to fight and no fuel to collect. In level four, you have to cross a guarded energy field to get to the other side, transporting one bomb at a time before the timer runs out.
After completing all four levels, the game gets tougher and faster. You'll have nine hits to keep you going, but your goal is to earn as many points as possible before you meet your end.
