Left 4 Dead 2 isn't giving the Killing Spree achievement.

[TITO2508]

#6202 In the past few days, I’ve been trying to earn a gold medal on every survival map. Yesterday, despite achieving a gold medal on every map, I didn’t receive the achievement. I contacted Steam support, and they told me to open a ticket here. I’m not sure if you can help me.

I forgot to mention that on Steam, I already have 42 out of the 43 maps with a gold medal, but as I said, the last map didn’t count.

Hello @TITO2508, similar to the older issue report, please clarify exactly which game and Steam achievement you're having trouble with.

With the game Left 4 Dead 2, and the achievement is Killing Spree.

Adding more info since me (and plenty of people online) still have this issue. I know this game is old and many people might not care but this is an extremely frustrating issue since I spent a good 7+ hours for this one achievement to get gold on every map (and multiple times for the bugged one).

It's specifically about the "Killing Spree" achievement, which requires you to get a gold medal on every survival map.

In-game achievement tracker stays on 42/43 and shows me I haven't completed "Boathouse - Death Toll". After googling and troubleshooting a fair amount this seems like a common problem and I've tried every suggestion I could find like the following;

• Replay this specific map multiple times (even getting to 10 minutes again)
• Loading the map on official servers, local, via console, every possible way
• Restarting game, steam and pc
• Verifying integrity of game files
• Completely re-installing the game
• Disabled any mods
• Earning different achievements to see if it would force a re-sync of sorts
• Reloading every single survival map to see if maybe it was secretly another map that wasn't updating properly.
• Checking the stats page in steam to see my survival stats, this shows me I have all 43 gold medals

Despite all this I can't seem to make it unlock this achievement for me.

I've had contact with steam support but they just provide me with bot responses and no other tips.
