I just played the game and there was one thing that mainly bothers me - Lag.
How don't know how to fix it, but like the most games/some I don't know - That you go into a checkpoint and you cannot go back,
Eg. Going down stairs, all the sudden an explosion started and all the ceiling stuff falls on the stairs behind you which you can't go back and while it does that it removes the whole place that was before the stairs. If you understand what I mean.
And the things I hope to see in the game.
Sensitivity - Both Menu screen and in-game
Able to pickup weapons.
Headshot, Kill Accolades.
And hands on the gun.
And some usually graphic settings.
And anti hack /
I also want you to have HP screen and able to regenerate health.
500 health was too much 100 ~ 150 would've been fine.
And dead bodies on the ground
Overall it was pretty amazing for a FPSC game.
