Hey, sorry I couldn't review your submission back in time to rate due to work.
It looks like you are very dedicated to this ambitious game so it'll turn out good for sure. Sadly, my pc is very much strugging to run it in decent fps (it looks like the specs are more demanding than Helldivers 2), so I didn't see much of the game. Hopefully, you'll manage to do some optimization as well, for example maybe the surrounding scenery doesn't have to be that detailed, or maybe LOD needs to be setup, idk I have no experience with unreal engine. Also, it seems some details like text printing speed and footsteps is not framerate independent.
