Mass Effect 3 - Preview @ Ten Ton Hammer

Ten Ton Hammer has a preview up for this game.     It seems to based on what Bioware showed in the ME3 demo at last month's E3.  Here's a snip about combat mechs:

Another interesting new twist to combat is the inclusion of heavy combat mechs that Shepard will be able to hijack. That is, assuming you’re able to take out the enemy unit piloting one without blowing the thing up in the process. It’s hard to say how frequently we’ll be given the opportunity – it may be only seeded in a few individual missions, or mechs may be seen extensively throughout the game – but considering the immense scale of the Reapers we can only assume that Shepard will be given the firepower to match when needed.
