Back when it wasn't F2P, it was a fantastic game.

Now it's full of those premium guys who think they are the best. And F2P's are stereotyped to be the kids and suck at this game.

Well, this game is only fun if you have patience and know how to use tactics. There are 9 classes, and only one CAN'T win a round. You have to use teamwork.
But wherever you go, on ANY server, you are guaranteed to see "trading x for x keys".
Yes, this game became a hat simulator.
No hats? YOU SUCK
F2P? YOU SUCK
Premium with hats? FREE BEER FOR YOU.

Unless you can get over those bad cosmetic items, and be limited to find only weapons as F2P, avoid.
If you have spare money, grab the cheapest item in the store to immediately become "premium" and have more stuff like possibility to "find" a hat.

3/5 from me.

you shoot the zombies with four friends and if you play versus mode some zombies are human players too

runs on potatoes because it's source engine, virtually infinite content due to mod support

it's very easy to pick up and play, general gameplay is like every other first person shooter, there are no progression systems so you don't get spammed with epic gamer emblems or level ups or whatever, you just play.
