Turn on the invincibility cheat
"HE GIVES STRENGTH TO THE WEAK"
then turn on the drunk cheat
"I'm as drunk as a skunk and twice as smelly"
To enter cheats go to options and to the cheat submenu. Hit triangle to enter them
So u will stumble around and won't die. Get a high wanted level. Be pummeled by bullets that knock your drunk ass down. You just get back up and keep stumbling at enemies. Too bad you can't attack anyone while drunk. Its still pretty cool.
