The game is a third-person arcade shooter, as the character aims and fires weapons at alien enemies. There is no blood or gore, but players shoot to kill and slow-motion effects add some drama and sensationalism to the action. The game also supports gun-like peripherals, such as the Wii Zapper and Top Shot Elite. The player doesn't target humans -- only aliens. Some scenes might be disturbing for kids, such as an alien crawling out of a (fake) human's body, as it screams, and an explosion that blankets a large part of a city.
