Several level options are available. First, a letter is chosen, which controls the environment settings: what bad guys are available, their accuracy at attacking, whether or not the player's diagonal shots bounce off walls, whether running into a wall will simply block or kill you, and whether the hives have a partial resistance to snipes' shots. The next choice is a number, which controls the maximum number of snipes that may exist, how many hives are initially created within the maze, and how many lives the player is given.
