No, the Mutant and Power armour use the SAW.
The idea is that the MG and Minigun are too heavy for a human to move and fire (too much recoil or whatever you wish to think of it).
That is why the MG humans can only be defensive (they need to setup the position and fire stationary) (just like vanilla machine gunners) So I want them to use the sit down animation MG(Maxim).
(This would technically be like the browning M2 Heavy Machine Gun [not a maxim] but we don't have one of those!
)
The SM and PA Machine gunner have the augmented strength to carry an MG into battle and fire from the shoulder. (So I want them to use the SAW)
The 'Back Pack' you added to the Minigun SM and PA is what shows it is a minigun and not a Machine Gun. (that and the fact that it stands and fires rather than doing the MG squat)
The Units we have are:
SM Machine Gunner (SAW) [Currently has the Maxim]
T51b PA (SAW) [currently has an AK47]
Heavy Machine Gunner (Maxim) [currently has SAW]
SM Mini Gunner (Maxim+Back Pack+Stand Animation)
SM Gauss Mini Gunner (Maxim+Back Pack+Stand Animation) [We talked about maybe adding a high voltage warning to the back pack]
PA Mini Gunner (Maxim+Back Pack+Stand Animation)
PA Gauss Mini Gunner (Maxim+Back Pack+Stand Animation) [We talked about maybe adding a high voltage warning to the back pack]
Heavy Gattling Gunner (Maxim) [needs back pack]
Heavy Gauss Gattling Gunner (Maxim) [needs back pack+Voltage]
Does that make it clearer what I mean?
The Upgrade goes Machine Gun ---> Minigun(Gattling Gun) ---> Gauss Variant.
Thus phasing out Machine Guns.
(Although oddly the M2 was always more powerful than the Mini Gun, particularly in Tactics) (the M2 may not have been in F2... but it was freaking awesome in Tactics.. Robo Shredder!!)
