For 3-4 players, playing time around 60 minutes.
Go down in the dungeon. Kill everything you meet. Backstab your friends and steal their stuff. Grab the treasure and run.
Munchkin Lite has all the same dungeon-crawling, pun-making, backstabbing madness of original Munchkin, but with 115 cards, it's the perfect size for three to four players. Take it anywhere, and play it in an hour!
