I jumped straight into the mechlab and made noob's first glass cannon with all ammo-based weapons and virtually no armor. Got my ass deservedly wupped. I love it, hope you add a merc career mode or something, MW2:M was my favorite and I only ever got to play a little bit.
No comment on the mechanics or visuals, they're both perfect. UI could use some work in some places but if the obvious good parts are any indication of the intended style then you've already got it down. Balancing on the chaingun is also a bit off, like you're shooting super-hot BBs. But if there's going to be infantry around to mow down someday then that's not a problem. It may also just be me ignoring the different armor types and maybe it's super effective against beam-reflective or something.
