Lol, don't tell them that Mas, they'll think there is something actually wrong.
You actually have seen mechs walk in a teaser video I belive, but the main reason you haven't seen mechs walking in game is that we've been doing quite a lot of research and discussion, as well as functional testing of what the truly best way to implement the animations is. In all honesty, true programming of Mechs walking hadn't started until recently, as we the programmers had to teach our selves quite a lot to be able to implement them (everything from IK and animation blending to the physics and entity system of the engine).
All that said, you have nothing to worry about, as making mechs walk, and torsos twist is WELL within the capabilites of our team. Actually, that isn't the only major project we have, we also are working on custom weapon grouping, vehicle fire-mode switching (group, single, alpha), heat effects, game rules, and general awesome

. We've got a lot, but luckily I'm working with a great bunch of programmers that I really have confidence in (we have yet to be unable to complete a task, unless directly limited by the game engine itself).
The mektek forums can settle down, we are doing just fine (I really do wish sometimes you could hear our dev converstaions, they would really ease a lot of general fears).
