Your objective is to repel the attacks of these organisms and keep the eggs in the incubators safe. To do this you have an arsenal of weapons, mines and blockers available.
In the Adventure Mode you will be in charge of the incubators for 40 rounds spread across 5 different worlds. Each world has 8 rounds in which you will unlock weapons, special powers and enemies.
Choose a scenario amongst the 5 available and try to keep your incubator safe as long as possible. Each new wave of enemies will be tougher and you will need all your skills to achieve the best scores.
