Im hooked

I've bought so many games only to return them in favour of games like Rainbow Six Siege.

But theres something about this game that has hooked me right from the beginning. Its so fun and the mechanics just work. Theres only a couple of minor bugs that break immersion (where is the torch light coming from??) but they are minor and the game comes together right from the beginning.

You guys were correct in saying this game was underrated.

Question. Am I suppose to be able to use focus shot from the beginning. Ive spent two skill points on it but cant seem to activate it.
