Tentacle Wars HD is a strategy game that takes a bit of mathematical understanding along with a lot of puzzle solving skills. Battle microscopic cells as they try to invade a dying alien and save the entire species with the stretch of your tentacles.
Players are in control of the antibody cells. The goal is to turn all cells on the board into good, or green ones. To do so, an antibody cell must transfer its own DNA into the red and blue cells with tentacles that reach out and attach themselves. The antibody cell must be stronger than the bad cell or the latter will take over and turn all cells into mutations.
