Upgraded edition of the arcade shooter (released on Dreamcast and PlayStation 2 subsequently). The arcade space blaster is best known for the BUZZ system for bonus rewards based on how close players come get to enemy bullets without taking a hit. The vertically scrolling shooter features a force field that surrounds the player's vessel. Any shot that passes within the field charges a special "Neutrino" gauge at the top of the screen and brings in bonus points. Based on the arcade hit of the same name, this Dreamcast port features weapons upgrades, fast-paced shooting action with tons of particles, and a storyline starring futuristic heroine Kei-Lambda-Oread. This upgraded Xbox "Extend Edition" features Xbox Live support.
