Walkthrough: Basement Killing
Objectives:
Ok, this level is pretty straightforward and no two players are likely to complete it the same way. In any case, you'll have to find a way to get your weapons past security (reminds you of the Anathema level doesn't it?). The trick to pulling this off lies with taking out the patrol guard dwelling by the weapons drop point area. Take his clothes and drag his body in a concealed area. Now you can pass through metal detectors with all your weapons in tow. Don't like that option? Assume the identity as the pizza boy and await Sidjan to call up Domino's (no, not really, but we can imagine can't we?)
Deposit your guns down the laundry chute, then walk through the metal detectors with the pizza. Once inside, head downstairs to collect your guns. Don't dawdle, because the guards won't take too kindly to you being down there.
Watch out for the scattered potato chips, or you'll risk alerting Sidjan. Once you're close enough to him, pump some bullets in his head and enter the elevator (which now is "magically" operational, go figure).
