The first trailer for Griptonite Studio's Assassins' Creed: Bloodlines (PSP) was released by publisher Ubisoft today.

The Christmas-bound title picks up right after the events of the first game, serving as a connection to the upcoming sequel. Bloodlines promises a level of gameplay similar to that of the original game, but it also expands on the concept with eight new mission types.

Sony's annual Destination PlayStation conference is underway, with confirmation that Rock Band, Assassin's Creed, LittleBigPlanet and MotorStorm are all PSP-bound.

Little is known regarding each game. Joystiq reports that Rock Band Unplugged will sport an in-game music store through the system's wireless capabilities, and adds that LittleBigPlanet PSP is being made "in conjunction" with creator Media Molecule.

Rock Band Unplugged will be "launching exclusively on PSP," according to Sony PR. Assassin's Creed will be "an exclusive installment," and LittleBigPlanet will pack new levels and areas "specifically created for the platform."

As for MotorStorm, the portable rendition of Evolution's racing series is said to feature the "breathtaking yet lethal and unpredictable setting of Alaska." It's dubbed MotorStorm Arctic Edge, developed by Pursuit Force veterans Bigbig, and will also hit PlayStation 2.

LittleBigPlanet, Rock Band Unplugged, MotorStorm and Assassin's Creed PSP are due out later this year. Expect more details once the non-Sony games, Rock Band and Assassin's Creed, are officially announced by their respective publishers.
