Borderlands 2 - Previews @ G4 and Stuff

Two new previews for this game have been penned, the first hands-on preview
comes from G4:

A quote on the Mecromancer class:

First up, the Mechromancer, a riff on the Necromancer class seen in other games. Borderlands 2’s take has her summoning a ‘pet’ as her action ability, however that pet takes the form of Deathtrap, a devastating robot that rips enemies to shreds and can be upgraded to cause explosive area attacks. While the Mechromancer’s skills are still to be honed, expect to see skill trees dedicated to boost Deathtrap as an offensive weapon, as well as other non-pet skills that yield different gameplay styles.

Stuff has the other hands-on preview.  A quote on the skills and abilities:

Borderlands' range of skills and abilities has also been expanded for the sequel. Our new favourite is the Thought Lock, a tricky little number that turns your enemy against its teammates. When the enemy dies, the Thought Lock travels to the nearest live one, who will then also turn on its own kind.

From VG247 comes word of the ESRB rating; M is the word here; M for Mature and a
17+ Rating. A quote from the description:

“This is a first-person shooter in which players join rebel forces to take down an oppressive corporation on the fictional planet of Pandora. As players explore open-world environments, they complete missions to gain experience and increase their characters’ skills/abilities. Players use machine guns, sniper rifles, flamethrowers, explosives, and weaponized vehicles to kill human-like characters and hostile aliens in frequent combat. Firefights contain realistic gunfire/explosions; injured enemies scream and emit exaggerated splashes of blood.
