I would love to help with the development, if you need it. I gave up on my (honestly massive) project 4 years ago, called CQB that I was developing using the UDK, due to work commitments.
looking great, lots of awesome details that bring it up
one thing I didn’t particularly like is how small the lens is on-screen when using the sniper rifle. to me it feels it’d be painful to see and aim. and as you’re going for realism, I’d argue that when you use a sniper rifle you’d put it directly into your eye socket.
also if you’re sniping it’s nice when games don’t let you see the surroundings so you can get suprised by other players cause you don’t see them
