Giant Mechs are always the best? (Interest/Sign-Up)

[Geminex]

Standard rounds, but the explosive parts use liquid nitrogen, trading a small amount of damage to lower the target's speed temporarily. If the NO2 is exposed to infantry or mech pilots then they take -1 from all stats temporarily and damage from frostbite.

I like this. Mechs rely on hydraulics. Suddenly freeze those hydraulics, and you're got major mobility issues. I wouldn't have this affect the crew, though, only the mechs.

I'd also drop the gas rounds.

The rest sounds pretty cool. I'd change the 'magnet rounds' into 'homing rounds' (basically rounds with a rudimentary guidance system and small control fins). I'd also recommend that most of the special ammo be restricted to pistols and shotguns, to give people a bit more incentive to use the former, and to make the latter a bit more viable as a main weapons system, since it's pretty situational otherwise.

Like. Let's make homing rounds globally usable, overcharge rounds only with Battle Rifle, Assault Rifle, pistol and shotgun, and restrict the rest of the special ammo to pistol and shotgun. We could theoretically have a guy who just carries around a pistol and spends the battle setting enemies on fire with guided incendiary revolver rounds.
Dibs on being that guy.

Edit: On second thought, I think the overcharge round isn't so great. How 'bout this.
Sabot round: When used in pistols it increases range by 100 metres to 300. Also increases armor penetration from 2 to 4. High recoil means a low rate of fire, though.

When used in shotguns, gives the shotgun the ability to penetrate 4 armor at ranges up to 400 metres, and 5 armor at ranges up to 150 metres. Only one sabot round may be loaded at a time, though, so after firing, the gun must be reloaded.
