I enjoyed FPS, especially tactical squad based shooters such as Rainbow6 (up to and including the ravenshield games). There hasn't been a decent tactical shooter released in FOREVER until now...
Insurgency is a recently released tactical shooter. It feels fantastic, looks great, sounds awesome and plays like butter. The guns feel really crisp. if you like tactical shooters, give it a try:

I have also been playing some Insurgency.
Coming from a competitive ($) Call of Duty on PC background, with experience in some other tactical shooters (Older Tom Clancy games, SWAT 4, Red Orchestra 2) this feels like an attempt at mixing CoD4 style movement (or at least movespeeds) with Red Orchestra 2 style shooting.
I think the current mix is a bit jarring although you get used to it. The movespeed is pretty quick and spastic, but the lack of movement blends (such as easily move from stances, lean while moving) makes the movement feel rather shitty to something like CoD4, which had a pretty big emphasis on movement in competitive, for a CoD game.
The shooting is very similar to Red Orchestra 2 in feel, but you're using modern warfare weapons for the most part, so the elegance of RO2's rifle gameplay is lost a bit on this style and it still feels a bit spammy, being that you can die in one shot and you have people who have horrible aim but will still kill you because after missing the first 5 bullets they clip over your model and hit you once and you die. It is pretty satisfying though 1b'ing someone across the map with an AK-M or equivalent, and there are a range of semi auto rifles and a couple bolt action scopes.
I still think it feels a bit funny and personally if I cared more I'd be campaigning for some movement blending (such as being able to lean while strafing and being able to hold shift breath zoom while moving) but that's just me.
It's in the middle between a tac shooter and a more faster paced game, which is a weird combo, and I think if it was a bit more tactical / slower or a bit quicker then it would be a better game.
