    Uchuu Senkan Gomora (宇宙戦艦ゴモラ) is a Sega Mega Drive horizontal shoot-'em-up game developed by Aisystem Tokyo and published by UPL. A port of the titular 1990 UPL arcade game Uchuu Senkan Gomora, it was released exclusively in Japan in September 1991.


    Unlike most shooting games, you control a heavy battleship instead of a small efficient glider, resulting in slow paced gameplay unusual for the genre. A shoots your weapons; the laser weapon from your main ship can be charged by holding A. B allows you to take control of a beam shot. While B is held down, the D-pad will move a box-shaped target on the screen and A will shoot beam shots toward the target. This beam is multiple times stronger than the regular shot and can hit any position on the screen, for the cost of losing controly over the ship.C is listed as "PAD MODE", when this is activated, the score counter turns gray to indicate itÄs activated. In this mode, pressing -not holding- B switches between moving the ship and the box shaped target. In each level, you can get orbs which give you either subships that shoot weapons diagonally or certain powerups (such as an automatically moving beam target or doubling the size of your ship).

    Pressing  START  at the title screen gives you a configuration menu where you can, among other things, choose to play one of two 2-player modes. Normal 2-player mode is 2-player cooperative (two ships on screen at once), while another option allows the second player to take control of the beam laser while you take control of the main ship.


    While the arcade version was released overseas (in the US under license from American Sammy under the name Bio-Ship Paladin), the MD version was only released in Japan — however an American title screen is present in the ROM and displayable if the region is set to US, which may mean a US release was planned (this is unconfirmed).

    UPL would go bankrupt shortly after publishing Uchuu Senkan Gomora (the later Task Force Harrier EX was ported and published by Treco.)


    Considering the hardware it was ported to and small rom sizes of that time, the game can be considered a faithful port. All stages and bosses are present, the ending is identical. The game displays an unusual high amount of objects on screen. The Megadrive version's main differences are:

    • The game has a hard coded autofire limit, making autofire generally slower.
    • Bosses appear after a short phase (3-5 seconds) that allows one background layer to scroll out, not instantly.
    • All Graphics are a tad vertically compressed, likely to compensate for the arcade versions wide screen type resolution.
    • Some different colors for bosses, enemies and backgrounds. The reason is that the game uses 3 fixed 16 color palettes for Player ships, objects and all enemies, only the background color palette is swapped each stage.
    • More slowdown, although the arcade version isn't slowdown free either
    • Additional scrolling background layers in some stages.
    • Background music in the bio station and submarine base have been swapped for an unknown reason.
