Sprite/illustration differences and possible dev intentions
Given the differences between Macil's ingame sprite vs. his profile pic, it reminded me that the player sprite looks even more different than his illustrated counterpart. This is probably a result of poor communication and/or different work timelines between the artists, but I wonder if Strifeguy himself is still supposed to look anything like a Front soldier in the campaign mode.
I say this because you never see your sprite when in first person, you only see it in multiplayer. It would make sense to have a generic soldier as a deathmatch pawn. Strifeguy was a wandering merc before joining the Front and he never was depicted as being given a uniform. The Order mooks also tend to not recognize him as a Front soldier in the "peaceful" and stealth sections and just take him for a normal civvie. I think they know what a Front uniform looks like so there's a good chance he's not wearing one. Of course, he still wears Front gloves in first person no matter what, but I doubt they wanted to make a whole different set just for deathmatch and they probably didn't put TOO much thought into it.
