I found some glitches O.o in LCS (Liberty City Stories) for PSP
-1. Go to the Stauton Island Ammu-nation and take a motorcycle, then get over the counter and then back up into the two bookcases in the back and you'll fall in to hell

then u die!!!! jk, you just fall in front of the road!
-2. Get into your garage and get a PCJ, any garage, then crash into a corner of the wall, (i recommend not doing this) once you fall into hell, you'll NEVER come out!!!
-3. To kill a police without stars
-a Get a car and go hella fast, once your right next to the officer, JUMP OUT

and they get run over by a car without anyone
-b Get a motorcycle and run over the the officer, REALLY SLOWLY and don't hit him hard, enough to make him fall and keep doing it until he dies
-c attack a police to get a star then run and stand next to someone (gangsters are the best) then once the police attack you, dodge it (you dont have to) then it hits the victim, if its an armed victim then he will murder the cops, if its a ped the cop will own it unless the cop is really weakened by someone! ped = (arms vs. nightstick)
-4. This is obvious, everyone knows this, snipe the moon and it will get smaller and bigger!
-5. This is also obvious, keep tapping x to sprint forever!!!!
-6. Get more than maximum cars in your garage, i think everyone knows this too
-a Get a car to block the garage door from closing, then get the car and get in there
-b Get the car next to the garage, get out once it opens get back in the car and go full speed inside the garage
-c Get the car near the garage and push it in with sprinting OR another car!
-7. Get an exploded vehicle (including helicopter) fixed. Push the exploded vehicle with something (preferably a firetruck or an ambulance) and push it inside the garage get everything out of the way and once it close get near it and it opens and you'll see your broken down vehicle into a shiny new nice vehicle
