This unlicensed NES-only version of Tetris features 2 double player modes. These modes are competitive and co-operative, both for human and NPC second player. Has 3 Soviet music tracks. Soviet dancers appear after clearing 30 or 50 lines (depending on stage). This game has only been on the shelves for 4 weeks before a lawsuit by Nintendo forced Tengen to remove this game from sale and destroy all the remaining copies.
