Omega Boost is a three dimensional shmup developed by Polyphony Digital (Makers of the famed Gran Turismo racing series) for the Sony PlayStation.
In the game, players take control of the Omega Boost, a giant robot or mecha in the style of famous Japanese Anime such as Mobile Suit Gundam or The Super Dimension Fortress Macross. The player is charged with travelling back in time to stop an artificial intelligence called Alpha Core from altering ENIAC, the first computer, and thus making itself more powerful in the future. The gameplay takes place on rails, meaning you must travel where the game takes you in the same style as titles like Nintendo's Star Fox or Sega's Panzer Dragoon. However, this rail-shooter element does not hamper your freedom to fly where you choose. On some stages, you have complete control of Omega Boost, specifically areas where you are in Planet ETA's atmosphere. Other stages limit you in terms of speed (falling through the timeshaft).
The "Boost" part of the mech's name comes from Omega Boost's booster pack, allowing the player to move in any direction and circle strafe enemies with a scanning and lock-on feature. Omega Boost also learns the Viper Boost maneuver once it is levelled up. Viper Boost, when engaged, will cause Omega Boost to glow blue as it tears through enemies on screen. Destroying enemies will cause the gauge to refill incrementally. However, the game can be completed without ever using Viper Boost. If Viper Boost is used, your final ranking will have "Pixy" added onto the title, proving you used the attack during your play.
The game has high production values with a few music tracks by the bands Loudmouth and Static-X. The game also features a live action introduction and mecha designs by Shoji Kawamori of Macross fame. Being released late in the PlayStation's life, Omega Boost is said to have some of the best graphics on the console with parts of the game running at 60 fps. The game was critically panned by many publications for being too short (Nine levels with nine unlockable special missions) and simplistic. However, it is still considered one of the best Macross style mecha simulation games produced and is thought of by many as a sleeper hit due to its poor marketing. (Wikipedia)
