I bought this game mostly for the multiplayer mode (I had Perfect Dark, but I sold my N64). The Prima's Strategy Guide says I can battle with up to 10 computer- controlled 'bots, but the game allows me to use only four at a time. Is there something I need to unlock, or is there a code? Also, in the Night Shift mission, I can get to the Security center just fine, but I can't find the stairs I'm supposed to take to get outside once I've unlocked the tower exterior and deactivated the laser trip wire system. Where is the door that leads out? I use the janitor's closet/ventilator shaft to access the security center, if that matters. Thanks in advance.
