Step into ancient Japan, where the imperial emperor has ordered you, his most trusted samurai warriors, to defeat the evil warlord Tanaka Masamune. But be warned, Tanaka is no ordinary enemy; he is protected by a powerful curse that makes him invincible to even the strongest warrior. The only way to beat him is to steal the magic stone from the handle of his sword – but first you must escape from the dungeon his henchmen have thrown you into. You have one hour to break free and complete your mission; any longer and you pay – with a fate worse than death.
