So it's been a year since I played this game. And I think this is the great time to write a review about this game. Tbh, I enjoyed this game a lot.

1. Something good about this game: Though this game was released 15 years ago but there're something that I feel impressed.
- The AI Director: Yes, this is an algorithm that will manage the match depend on survivors' situation. Idk why but when I was playing a expert match with my friend and that moment I and another friend were back and white, one is dead, I see three defibrillator near each other, I thought that maybe pills but AI Director had able to change the item. but sometimes the Director gives us some bullsh*t situation but that's okay xD
- The AI of survivors and infected: I love how the AI of the survivors is pretty stupid but the AI of the infected is smart. That's maybe a challange for the single players, the common infected can run front of the survivors to deal more damage. The special infected are smart, too (I hate Smoker and Jockey). I love how the behavior of the commom infected are very similiar to human, just show that they used to be a human.
- The details: This is a 2009 game but it have some details that some new games don't have though it's just a small detail like environment, infected intereact with the flashlight (not like a co-op zombie shooting game from "creator of Left 4 Dead"). Things I like most are the gore and ragdoll (exactly the motion capture), which make the animations of the infected are so smooth and nature.
2. Something not good about the game: Still something pretty annoying in the game
- The hitbox: Yep, like sometimes I meleed the infected, I heard the hit sound but somehow they didn't die
- DDoS and hackers: Every online games have to deal with this, not only L4D2.

Overall, L4D2 is still worth to play though it's been 15 years old. Of course, I will continue play this game for long long time. I give this game a W and recommend you guys to play it once in your life
