Turtlerock came up with the IDEA and basic tech demo valve was shown back in the day... they really didn't MAKE Left 4 Dead well... left 4 dead. that was entirely thanks to Valve's dev team. that's why Back 4 Blood flopped so hard alongside the technical stuff. they had no darn clue what made L4D 1 AND 2 remotely popular... cause they didn't truly make left 4 dead, just it's idea and basic structure.

out of all the devs in the ORIGINAL L4D Credits. only 6 are from Turtlerock, the rest are all Valve Employee's.
left 4 dead 3 and half life 3 are probably in the making but kept secret , look at cs2 release , its was announced 2-3 weeks before coming out.
Back for blood was not a good game👎
