This review is purely based on my experience of this game. I tried my best not to let other games affect my view of this game too much and rate everything on an for this game appropriate scale! This review does contain spoilers, some of which may not be marked as such!

L4D2 is getting old and you can see it.
There are various HD mods for various parts of the game but thanks to the 32-bit nature of the game you're limited to 4GB of RAM which will be reached very easily when using said mods, resulting in game crashes.
Left 4 Dead 3 when?
☐ Very good

☐ It's just gameplay

☐ Just don't
L4D2 is not just a coop survival zombie shooter.. IT IS THE COOP SURVIVAL GAME EVER!
Everything else is just a copy.
Just kidding.
Anyways.. You try to get from one side of the map to the other side. From one safe room to another.
With your friends. While killing hordes of zombies and special infected like the Hunter or the Smoker.
Or the Witch.. Which you should definitely give a kiss, because it's good luck. Trust me. (One of the voice lines of Nick, my main character)
Gameplay is a lot of fun the way it is, especially when playing with friends, and given that there are thousands of custom campaigns, it should never get boring.
Besides the normal campaign mode there are of course other modes.
Like the survival mode in which you have to.. survive.. in a single stage of a campaign for as long as possible.
Then there is of course the PvP mode, which I never play and, even after thousands of hours playing Left 4 Dead 2, am still missing the achievements for.
And a few others.

Everything in this game sounds pretty realistic.
It's definitely at a level were you can use the sounds of suspects to your tactical advantage.

Do I have to say much about this? It's 18+.
I mean I started playing L4D2 when I was 15 and it was literally the first 18+ game I was allowed to play (my dad took that stuff very seriously).
It's still a zombie survival shooter, in which you kill zombies, and sometimes your own team because of trolling or bad aim, or because they're once again running around in front of you.

The game was released back in 2009. You could probably play it on your smartphones hardware.
Most of you probably haven't even heard of most of these specs.
Anyways. Keep in mind the game is 32-bit. Might cause some issues on Mac as far as I know.
Also causes the game to be limited to 4GB of RAM.

☐ Floppy Disk
☐ Old Fashioned
☑ Workable
☐ Big
☐ Will eat 10% of your 1TB hard drive
☐ You will want an entire hard drive to hold it
☐ You will need to invest in a black hole to hold all the data
At the time of writing this review the game was a whopping 13.93GB on Steam!
☐ Just press 'W'
☐ Easy
☑ Easy to learn / Hard to master
☐ Significant brain usage
☐ Difficult
☐ Dark Souls
The game isn't really hard. It does of course get more difficult on higher "difficulties", but when playing with friends it should still be easy enough.
If you don't have friends to play with.. Welp you're f'd. The bots on this game won't help you in the slightest on higher difficulties.
If you really don't have friends to play with and you have to play with bots or with random pubs (public players) then I'd say "Difficult" would be a better fit for higher difficulties.
☑ Nothing to grind
☐ Only if u care about leaderboards/ranks
☐ Isn't necessary to progress
☐ Average grind level
☐ Too much grind
☐ You'll need a second life for grinding
There is no grind, no leveling, no unlocking of stuff, no nothing.
You can do anything and everything from the start.
The only grind you might find is grinding for one of the new achievements (killing 53599 infected).
☐ No Story
☐ Some lore
☐ Average
☑ Good
☐ Lovely
☐ It'll replace your life
Left 4 Dead 2 pretty much continues, and even includes, the story of Left 4 Dead 2.
You can either play the Left 4 Dead 1 campaigns with the L4D1 survivors or you can play the "new" (lol review 15 years later calling them new 
) L4D2 campaigns with the new survivors 
Nick, Ellis, Rochelle and Coach.
You'll even get some interaction between both survivor teams! And a lot of cursing from Nick.
☐ Long enough for a cup of coffee
☐ Short
☐ Average
☐ Long
☑ To infinity and beyond
Left 4 Dead 2 got a lot of replayability especially thanks to it's coop nature and the fact that it got thousands of custom campaigns on the workshop.
Especially with friends you might easily get a few hundred hours in (if you don't already got them).
At the time of writing I got 3760 hours of play time in L4D2.
According to How Long To Beat the "main story" is about 10 hours which is pretty accurate considering that a normal campaign is usually about 30 minutes.
A completionist run could be anywhere between 36 to 143 hours.
☐ It's free!
☑ Worth the price
☐ If it's on sale
☐ If u have some spare money left
☐ Not recommended
☐ You could also just burn your money
The normal price on Steam is a whopping 9.75€. For a game like L4D2 that's basically free.
☐ Never heard of
☑ Minor bugs
☐ Can get annoying
☐ ARK: Survival Evolved
☐ The game itself is a big terrarium for bugs
The game does indeed have a few bugs, must most of the time you won't notice them. Or maybe I don't notice them anymore? I don't know 
If we want to consider the bad team AI a bug, then it's probably the biggest one in the whole game!

L4D2 is definitely my all time favorite game, yet I cannot and will not give it a 10/10.
Why? Just cause.
It's a 32-bit game which is still being updated every now and then by a team from the community.
But it will never get that 64-bit upgrade which would allow us to do so much more modding stuff and possibly even increase the games graphics up to a point where it could compete with modern games.
The limitations introduced by its very 32-bit nature are just a huge downer for me.
I've spend hundreds of hours trying to fix my mod collection because some mods made me go above the 4GB RAM limit and you never know which one it is because there isn't any proper way to debug it.
But even then, even without mods, or just a few, smaller mods, the game is still a lot of fun, especially when playing with up to 3 other friends.
