The Mass Effect 2 website relaunched yesterday with a new look. While renovating the site, BioWare also added a couple fresh trailers for the game.

The first trailer showcases Tali, the quarian mechanic who acted as one of your NPC companions in the first game. She'll be a playable character in the second installment as well. We're shown a brief clip in which the two of you visit the quarian flotilla, the large fleet where Tali's entire race lives in lieu of a homeworld.

The second trailer's a preview of the Adept, one of six classes in the game. The Adept relies on biotic powers (essentially the game's "magic") in combat. Biotics in ME2 are able to swerve around corners, allowing you to take out enemies cowering behind cover.
