Absolute top tier multiplayer experience, amazingly thought out map layouts and well rounded, lovable classes. However the game is very, very slow on updates due to VALVe not focusing many people on it so they are few and far between. This issue would not be that worrying but the game is plagued with absolute no life basement dwellers hosting aimbotting bot snipers, so i would definitely recommend going to community servers in which bots cannot join currently. Also the tutorial could use a LOT of work and the settings you get slapped with on first boot are abysmal, most of which need console commands to change.

[Edit 1]
VALVe has begun updating the game more recently, hopefully this keeps up. Hoping for a major update is way too much though and we should be grateful they aren't completely abandoning this (near) masterpiece. Besides with their current track record a new major update would probably be overall negative for the game.

[Edit 2]
They stopped. Updates are few and far between again, if at all. The bots are still in full force, if not more.

[Edit 3]
Huge ban waves decimating bot counts, lets just hope they keep it up.

Multiplayer - 8/10

Run it back. RUN IT BACK.

They fixed the game, faith restored.
