Nice! But first did you make all models, textures and codes yourself?
When i joined the game and i selected a gun it zoomed in and i could not move which way i was facing so i could not aim is that a bug?
Second, the maps
Maybe make a real door and not a random texture on there that would let it feel much better and it looks out of place in the map.
In the lobby (is it a lobby i could not really tell?), the stairs are kind of messed up.
Third thing, I really hate it when people just copy work from someone else because i see that this map is ‘Agency’ from Arsenal.
I played this game for about 7 minutes and that is what i found.
