Samuel, you should have posted these here first instead of posting them in C&B3...meh, Ill have a look.

Fatality - 1kg Hardox teeth seem rather small. Id reduce the weight of the shell by taking off about a mm of Hardox and make the teeth bigger...say...3kg. Also, how many kg is the single CO2 tank?

Axetra - 4kJ of force...your axe is going to die. Beta could hardly manage 3kJ and that was with magnets on metal floors...seriously lower it, at least by half. Terrorhurtz has like 500J of force in its own axe...maybe more, and look what it can do.

Mad Dash - You dont need a monocoque for the scoop. Do you know what a monocoque is? Think about that before you include it. Also...5mm titanium for the base? What about the rest of the armour?

V.ENO.M. - James Cooper has taken the name, actually. Venom, as far as I know, is a clone of Razer. Name aside, tracks are always a weak spot no matter how strong they are. Also, I doubt youll have IMMENSE pushing power with S28-400s, but whatever.

Ramminator - You state a sawblade on a wedge, when you shape says you have a box with a scoop in front. I see no wedge. Also, whats Asmaprene urethane? Care to explain?

Bubonic Plague aka Black Death 2 - Might be a bit optimistic with the amount of weaponry on there, and the power. Again, whats with the immense pushing power if youre running S28-400s? And no side ground clearance?

Walk Don€™t Run 3€˜n a half - Uh...again, tell us what this lovely Asmaprene is, and why you associate insane pushing power with S28-400s, please.

Paralyzation 2 - More Asmaprene...explain. And a great pusher. Again, tell us how. 3.5mm ground clearance might make you less manoeuvrable, so Id raise that.

And thats all I have to say on the matter for now.
