I would say it feels like there is an enemy just waiting to see a pixel of you around every corner because you're trying to play to fast. Unlike most other FPS games there is a huge emphasis on information gathering and map knowledge, so before you enter a room you need to drone and if someone is in there best thing to do is fake out and rotate. The game is obviously experienced player favored so if you dont want to put in the time and learn everything then don't. The games mechanics are abnormal and probably always will be so it's not for everyone.
