They've recently released a list of achievements and trophies that players can unlock. Of interest to me are the achievements for games that your character can play within the game itself.
- High Roller - Win over 2,000 chips in a hand of Poker or Blackjack.
- No Dice - Complete a game of Liar's Dice without losing a single die.
- What About Hand Grenades? - Get a ringer in a game of Horseshoes in any game mode.
And, although not related to the above, I had to laugh at the following achievement...
- Bearly Legal - Kill and skin 18 grizzly bears.
