I have been playing this game for years off and on. Almost 1000 servers are still going and dozens of people each server. I am still waiting on Left 4 Dead 3 because Back 4 Blood was just trash and not even the same type of game. This game includes both LFD1 and L4D2 so just get this one. Also, the workshop is still legit full of mods and modders to make the game as custom as you want. Maps, skins, themes and sound packs. Try this game if you are looking for a legit game that is fun and still played that wasn't ruined by online only and season passes.
