This game is impenetrable to me. Even if you punch in a code you have no will always have no map, and you will always start with dick all health or ammo. Even if you could in theory push past this, the game is full of some truly loathsome trolly design, like the way forward being hidden behind invisible paths or random breakable blocks that you have to find with trial and error. To say this game aged poorly is putting it mildly.
