The mechs dont feel intimidating or powerful, id suggest giving them weight, in the game if you walk over a enemy player they dont die implement that aka stepping on a enemy kills them.

reduce the damage a human gun can do to the mechs 3 and a quarter of the mags of the compressor kills a mech, reduce it down to 4 or 5 mags, the mechs need a larger variety of weapons not jsut a 13 second missle and a minigun with 70 rounds bump it to 200 rounds, change the missle to idk a shotgun or stun gun, something to make the mechs feel like a real threat.
