Nemesis

The North American version of Nemesis features a considerably increased difficulty compared to the Japanese and European version. To balance this, the game spawns a fleet of orange enemies when the player loses a life to provide as many power-up capsules as possible to recover as many upgrades as possible. Also the North American version presents a continue feature (but only for three times). The title screen was also updated, showing an in-game reproduction of the promotional artwork behind the logo.
