BOH is an original, retro-flavoured game of exploration and action. You move in claustrophobic and dangerous battlefields searching for the Evil Masters.

This no easy task not only because of the traps-packed corridors and mind-blowing puzzles, but also because of the countless enemies that the Evil Masters throw at you more and more until you discover them - at that point, you will be attacked directly by the Evil Masters themselves, the hardest of them all.

Although your quests are made slightly less hard by the bonuses and power-ups scattered all around the battlefield, carrying out the missions demands lots of concentration and quick reflexes.
