In the recently-opened beta of Chris Hecker's SpyParty, one player takes on the role of an unassuming spy, tasked with completing several objectives in a soiree setting. The other player is the sniper, tasked with identifying the spy and taking them out. It's a simple premise, but the action is nail-bitingly tense as both players engage in a sort of inverted Turing test, trying to fool each other until the final pull of the trigger. If you're looking for a gripping but quick challenge, grab a cocktail glass and join the party.

Behind a closed door in an abandoned apartment building, a freelance spy is trying on a new pair of pants.

Thankfully for those of us who aren't reptiles, there's Mark of the Ninja, a stealth action game developed by Klei Entertainment that provides ninja excitement without the heavy shell or outdated surfer lingo. As an unnamed ninja, you'll use your weapons, skills and the powers of a mysterious tattoo to seek revenge for an attack on your clan.

Bam! Caught ya! Being stealthy is something we all do when creeping around the kitchen at night, going for that last piece of cake before anyone else in the house gets a crack at it.

Instead of getting busted and forfeiting half a slice of cake, though, you get blasted to pieces by a robot laser the size of your torso. Ouch!
