a beam weapon or laser weapon, respectively. Containers marked with a "P" power-ups the equipped weapon, increasing the pattern and strength of shots fired. Each weapon can be enhanced by power-up containers from level one to a maximum of three. Collecting excess "P" powerup containers restores the hyper shield meter. The beam weapon is upgraded to fire a wide wave of strong beam shots, while the laser weapon is upgraded to fire a large criss-crossing pattern capable of striking more nimble enemies. History This game was released in Japan under the name "Battle Unit Zeoth". When Jaleco began planning for the US/Europe release they renamed it "Jetpack". This name was later changed back to "Battle Unit Zeoth". It is thought that Jaleco changed the name because they didn't think American audiences would buy the game as it sounded too foreign.
