You play as "Polo" (a direct reference to/play upon Metal Slug's main character, Marco). Polo was spending a relaxing day at the beach with his prized football autographed by Joe Montana. Suddenly, he's kicked off the beach and his football is stolen by a kid and his musclebound bodyguard so that they may build the ultimate sand castle. It's up to Polo to reclaim the beach and his favorite football by engaging in a massive squirt gun battle. The game consists of two very long stages each with a boss fight at the end. You can submit your score once competing the game or losing all your lives.
