The demo had some interaction; the Postal Dude could shoot at individual bottles in a grocery store and they fall or shatter realistically. However the main new item we got to see is one of the game's new weapons; the badger saw. Imagine a living chain saw with a real (for the game) badger who is held by the Postal via handles. The badger can eat off human heads pretty effectively. Other weird weapons are planned and Desi told us that drivable vehicles will also be put into Postal 3 and hinted that they will be as different as Postal 3's badger saw or Postal 2's cat launcher.

Desi told us that in addition to the Postal Dude, people will be able to play as the Postal Babe, who will be modeled after Playboy Playmate Jennifer Walcott. In addition there will be three modes of play in single player mode; Good (join the police force); Bad (become a corrupt cop); and Insane (we will keep that mode a secret for now). Desi told us that several celebrities have signed on to appear in Postal 3; when asked if Postal 2's Gary Coleman will return Desi told us that he will make a very brief but memorable appearance.
