Own the rights?
There isn't much in this category. After killing women in the game, you can then look up their skirt and see their underwear. In multi-player mode, scantily clad girls dance suggestively. That's it.
Extremely violent, although done in a rather comical way. Players are free to run around killing people as they wish with a sundry supply of weapons. People can be decapitated with shovels, blown to bits with shotguns, lit on fire, peed on, etc. With the expansion pack, players can cut off limbs and cut people in half - causing intestines to litter the floor. Players can pee in someone's mouth, causing them to start vomiting, then chop their head off, and watch the barf spew from their next stump. You can't get much worse than Postal 2's violence. You can use cats as silencers as well.
Rather coarse at times - words like F*** are used quite often.
Check, check, and check! Players can smoke weed causing their health to raise, and also smoke catnip to go into slow motion.
None really. Postal 2 is done in a rather comical fashion.
