Invatris is a Super Tetris clone also featuring a classic Tetris section. It was made for the Space Invaders resource files competition, and therefore features the graphics and sound from the original Space Invaders. The original Super Tetris gameplay remained pretty much unchanged, but an objective was added to ‘clearing the blocks’ concept, where in Invatris space squids invade space ships and take them over by clearing the blocks in their bellows. High scores table for both game modes are featured.
Most described the game as overly difficulty and not introducing enough new elements into the classic Tetris concept.
