Hi Get Dovah It! 
Thanks very much your message! Thank you for you excellent encouragement! 
I hope you’ve had fun blasting some Gacrux aliens so far!
Sure, Assault On Proxima is like stylised Halo, or maybe Destiny, but in a more Hard Sci-Fi setting. The game is definitely intended to be a class based and cooperative shooter where the player can choose their prefered combat tactics or coordinate with other players to make a dope team to take down the alien invaders!
Really, the idea for Assault On Proxima came from my long time passion for classic Science Fiction such as Asimov and Robert Heinlein, mixed in with Aliens and Warhammer 40K. I wanted and want to make a traditional First Person Shooter, along the lines of, yes, Halo, and or Quake or Tribes, but in a new and original Sci-Fi Setting. And with a unique artstyle that is appealing to young and older players alike.
I am not aware of the Babylon Project. So that was not an inspiration as far as I know. Hehe. Is the Babylon Project something to do with Babylon 5? I’m certainly a Babylon 5 fan!
Assault On Proxima was developed by only 2 people; myself doing the 3D Art, Level Design and Game Design, and the Lead Programmer, Andrei Tomei, who yeah, did the Programming. I will be honest, the development was significantly expedited by Content Packs from the Unreal Marketplace, without which, I feel we would have needed a larger team or a lot more time to develop Assault On Proxima.
Thanks for your cool questions Get Dovah It! I hope you can join us to play Assault On Proxima when it enters Steam Early Access release, hopefully in March. If all goes well, maybe we could even bring the game to the Epic Games Store later this year!
