OK, so:
I’ve figured out every role and the dev, and here’s the list:
Primary Dev: Nick
Animation: Nick and 6.7.2019
Character Design: DOBN/LiveDagger, MilkTea, Pheonix
Level Design: MilkTea
VFX & SFX: Unknown
Musical Scoring: Unknown
And there it is.
Forgot the other components of the Game Dev team, so you can go ahead and clear it out for me so I can make another role identification post.

I enhanced the version of the opening cutscene. The logo shows and fades, but your player name is used in the dialogue.
For example: If I type my player name as “Freeman,” then the stickfigure would speak like this:
Rise and shine, Mr. Freeman. Rise and shine. Not that I wish to imply you have been sleeping on the job. No one is more deserving of a rest. And all the effort in the world would have gone to waste until… well, let’s just say your hour has come again. The right man in the wrong place can make all the difference in the world. So, wake up, Mr. Freeman. Wake up and smell the ashes.
(As the stickfigure speaks, the names of the devs are shown.)

So another faction.
The Dragon’s Pledge, a former United States Marine Corps battalion, is the number 2 largest faction with over 200,000 units. The faction is sort of like Combine Overwatch, but bases on communist belief and gets their technology from old dealers.
Their technology comprises of Gunships looking the same like the Combine’s, APCs, etc. They also have the same mission as Argon Corps.

The helpful scout on the menu.
