Alien Catcher is a co-op action game about two secret agents and a city overrun by aliens. While you were busy on an important mission, the invasion began, and now the government has given you an even bigger job: clean the city of every alien.
Play alone or with a friend as a team of agents. Each stage has a set number of objects to collect, shown at the bottom of the screen. Collect them all to move on to the next stage. The aliens will not make it easy: they come in different types and grow stronger with every stage, so use your weapons to defeat them. Your remaining lives are shown at the top of the screen. Working together is the only way to beat the later stages.
