If you're happy to spend $10 on a decent shooter sandbox to mess around with your friends in, by all means buy the game. If you're looking for something else read the rest.

This game had some real potential in 2013. It was a fun shooter that added little notes of realism that weren't common yet, like rain on you helmet visor, or audio being different with the mask open vs closed. I commend the one remaining dev for not giving up, but this game is dead and gone. Even if they turned it into that original vision perfectly, the game would feel outdated and generic by modern standards. It sold on realism, tactics, and pretty graphics. All of those are available in dozens of other completed indie shooters. I hope I'm proven wrong, but don't spend your money on hope here.
