Part shooter, part puzzle game with heavy influence from classic arcade games of the 80's.rnThe goal of Fortitude is to break through the multi colored barrier by shooting colored balls at it. Match 3 of the same color and they blow up. Once you break through the barrier, you must shoot the Red King 3 times to win the round.rnSounds simple, right?rnWell it's not a simple task... the Red King will launch fighters and spit energy balls in an attempt to destroy you. And if you do manage to break through his barrier, watch out. Once the Red King can see you, he will fire his unstoppable hyper beam, so you will need to keep out of his line of sight if you want to survive.rnIf you do manage to defeat the Red King, you will be treated to one of 2 bonus games, where the goal is simple: shoot things for points.
