Respawn Entertainment unveiled two new Titanfall titan classes, the Ogre and the Stryder, at the Spike VGX Awards in Los Angeles over the weekend.

The Ogre class Titan is a slower, heavily armoured mech. Its finishing move is to rip the arm from an enemy mech and use it like a weapon.

At the opposite end of the spectrum is the Styder class, an agile, fast-moving mech that relies on manoeuvrability to best enemies.

Respawn is a new studio founded by Call of Duty co-creators Vince Zampella and Jason West. Set in the near future on a distant frontier torn apart by war, Titanfall drops players in the middle of a conflict between the Interstellar Manufacturing Corporation (IMC) and the Militia.

The FPS features a mix of on-foot parkour-style wall running, massive double jumps, and mech combat.

Titanfall is due out on March 13, 2014 for Xbox 360, Xbox One, and Windows PC.
