ive found a few neat glitches in the construct.. mostly in the ballards/swat room (scenario 2). go into the room where the swat members are spawning out if you keep knocking them down and not let them leave they will eventually just stand there frozen not in a fighting stance. the second one is with the ballards. first do the above glitch so the swat stops then walk over to the ballards they usually just run around and sometimes randomlly shoot. stand ontop of a crate that a ballard is standing next to, when you jump off ballard will start to chase you sometimes firing.. but now they will follow you...anywhere. the coolest thing to do with this is lead them to the swat platform training room (caged in one) but if you hit the button to start the game ballard will start shooting making it alittle more difficult since you cant hit him. to disarm him make him chase you then punch at him so he stops running do that a couple of times and he will disarm, now when you hit the button he will help fight the swat members and it will count on your score.
if he falls he will not respawn and the ballard/swat room will reset.
(leading ballard into the gun training room will also reset the sequence)
so far it only works with ghost in the black suit (scenario 2) and it also doesnt work with more than one ballerd there.
enjoy.
