This is a run and gun video game that can be played in single player and two player co-op modes. The game is based on a small group of soldiers, the Peregrine Falcon Squad, who came together to prevent various forces from taking control of the world. These forces include a rebel army and aliens.
Similar to Contra, you will run across the game background shooting at a continuous stream of enemies so as to complete each of the 6 levels. These levels span across different locations such as waterfalls, forests, military bases, garrisoned cities, and canyons.
At the end of each level, you will face and boss who is usually more powerful and much bigger than the normal enemies. Unlike most games in the run and gun genre, in this game, coming in contact with enemies does not kill you, instead, it gives you and the enemy an opportunity to perform melee attacks against each other.
Overall, the game was able to set itself apart from other side-scrolling games and also contains humorous elements which made quite entertaining.
