Multiple preset controller configurations are also included, with the default scheme using both shoulder buttons to strafe. Players can have their character always run through levels (instead of holding down a button), toggle in-game message text, adjust turning sensitivity, and increase or decrease the brightness. Both multiplayer modes require a Game Link Cable and a cartridge for each player.Ī number of options are available to customize play. The Game Boy Advance version supports cooperative play with a friend as well as a versus mode against up to three other opponents. Two types of armor are also available to help the cause, as are items like medkits, stimpaks, and health potions. The character can find nine different weapons to inflict damage with, from pistols and shotguns to chainsaws and the infamous BFG 9000. Players will battle 17 types of creatures across over 30 indoor levels until the vicious threats to humanity are finally vanquished.
