While it doesn't change the plot (such as it is), some of the difficulty levels in Postal 2 change the types of weapons NPCs use in the game, or the way they behave around you. Liebermode removes all the NPC guns, replacing them with melee weapons like shovels, police batons, stun guns, and scissors. (It actually makes the game a lot harder because they don't drop gun ammo anymore). Hestonworld arms everyone with guns. (Which can actually make the game easier since there's not only more ammo drops, but civilians will return fire at anyone shooting, including factions and cops. Monster infighting FTW.) Insane-o arms the NPCs with heavy weapons like rocket launchers, napalm, and WMDs. (But their shooting AI remains the same, so they're really more of a danger to themselves and each other than to you.) And if you choose the difficulty level They Hate Me, every single NPC in the game will attack you on sight. (This makes many of the plot items impossible to accomplish the "normal" way, but everything in the game has more than one solution.)
