Buy Now$5.99 USD or more


In claustrophobic, puzzle-riddled, dangerous mazes, surrounded by countless enemies, you hunt the Evil Masters down with the purpose of eliminating them and the pain they brought. Determination, concentration, and quick reflexes will be your only allies in your desperate quest...


BOH is a dungeon crawler where you need to solve puzzles, collect items, open passages, avoid traps, kill the Evil Masters and the minions they generate endlessly, and ultimately come out of the mazes in one piece. Keep cool, avoid the enemies as much as possible, focus on the labyrinths, and eventually you'll make it to the end.

BOH, thanks to its unique aspect and gameplay, is an immersive experience that makes you feel as if you were actually lost in those treacherous dungeons.

You can play any (unlocked) mission any time, and you can also decide how they look and sound by choosing freely one of the several themes available...

BOH is part of a saga that, as of writing, includes six different games.
BOH opens the story, with the Evil Masters bringing chaos to Earth. Huenison focuses on the fight against one of them, the eponymous character. Eventually the Evil Masters were repelled, but, as seen in QUOD INIT EXIT IIm, during their retreat, Huenison and his companions happened to pass by planet Suinio and decided to cause trouble there as well. Having witnessed the Evil Masters' cruelty, the Pemkians decided develop the defense training program that SkillGrid is part of. In MAH, years later, the danger came from the Apocalypser, the weapon that had been developed against the Evil Masters and that the Purifiers activated to destroy the Earth. Finally, KOG assigns a new task to the hero who turned the Apocalypser off.
