The alien invasion served as the inspiration for the game Alien Hunter Bros. We have no choice but to quickly take action in order to repel the attacking army. Players are in charge of their own squad and lead two agents into the conflict to stop the invaders and bring them to justice.
Aliens tend to take cover in treacherous environments that are tough to traverse. Players are able to triumph over these challenges by working together. One of you is going to fool about, while the other is going to keep it contained within the alien's ball.
