Check out my Hawken preview. I was lucky enough to get my hands on the indie-mech-fighting sensation at E3 2012, and found the experience very enjoyable.
Here's a taste of my Hawken preview:
"For E3 preview purposes, we played team deathmatch in a ravaged, future-dystopia city, filled with crumbling buildings and metal obstructions. Hawken does a good job making you feel like you’re in a vehicle, without it being annoying--the game moves differently than a typical FPS. There’s weight to your mech. When you lumber around, the ground seems to shake beneath your metal feet."
