Psy-Phi was a cancelled fighting game developed for the Lindbergh arcade platform by new development studio Digital Rex, a development group within Sega, headed by Yu Suzuki formerly head of Sega-AM2. It is the first arcade fighting game to incorporate touch screen controls. Shortly after location testing in 2005, its planned 2006 wide release was cancelled.
The futuristic fighter's premise casts the player as one of several warriors who are engaging in 1 on 1 combat. However, Psy Phi's twist is that the players will be floating around an opponent and relying on powerful blasts of energy as an attack. The premise of the game drew comparisons to Dragon Ball Z and Dreamcast game Psychic Force 2012. The game featured characters: Ays, Reid, Vient, Silva, and Ness.
Suzuki revealed that he enjoys Japanese manga adaptations of great science fiction works by the likes of Jules Verne and H.G. Wells where the main characters have super powers. Space Harrier actually came about because of this interest. Suzuki says the manga Babel II was his main inspiration in the creation of this game, and he had described it as "futuristic dodge ball".
Psy-Phi is an arcade game based on Sega's Lindbergh hardware. The project was headed by Yu Suzuki and incorporates a 29" touch-screen display for gameplay. An action-shooting game with 1-on-1 combat, players hovered in the air and competed with each other with attacks by trailing a path on the touch screen or inputting special symbols on the touch screen.
The game was showcased to an international audience at Japan Amusement Machinery Manufacturers Association along with other Lindbergh titles including After Burner Climax, Ghost Squad Evolution, The House of the Dead 4, Initial D Arcade Stage 4, Let's Go Jungle!: Lost on the Island of Spice, OutRun 2 SP SDX, Power Smash 3: Sega Professional Tennis, Virtua Fighter 5.
Psy Phi's graphics—one aspect of the game that were questionably because it was the first Lindbergh game to be shown publicly. The graphics at JAMMA 2005 were described as sharp, but they won't blow anyone away yet. The character models sport a high number of polygons and animate quite nicely. The special effects used for the various attacks are sharp and go crazy with particles and lighting. The stages shown were low-key open areas that weren't big on detail at that moment. The relatively unimpressive graphics were attributed to the fact that the game started development for the Sega Chihiro Arcade hardware.
The original release was planned for spring 06, but the arcade units were called back in March 6 (the units were still in shipping and had yet to reach arcades). It was then unknown whether the game was canceled or called back for further development. Some units were previewed at trade shows, as well as some arcades receiving units for beta tests (most notably Gameworks).
