I put in about 45 minutes including multiplayer. It's simple, but super impressive work. The gunplay and mechanics are exactly as realistic as I want. I immediately disabled the narrowed field of view comfort setting and was not bothered at all. (I left turns on snap--smooth turns = hurling for me.)
The gun selection is great. I would like to see names and a couple of details about the guns in the UI as I'm not up on all the models.
It would be cool to be able to select different shooting range modes so that I could practice long range with the sniper rifle for example.
A few more maps and I think you'll have a game with some staying power. Would like to see more players jump on. There were some no bots servers with barely enough players to keep me interested for a bit.
Definitely worth a download and a tip to the author!
