10 Impossible Video Game Achievements That Totally Broke You

10. “Nothing Special” - Left 4 Dead

While it did appear as an all-out, action-packed, zombie-massacre based on first impressions, Left 4 Dead is undoubtedly a survival horror experience. A bloody tense one at that.

Cooperation is the key to victory here - especially so, if you want to earn this tough-as-nails achievement. While completing all the campaigns on the hardest difficulty is a tough enough job, “Nothing Special” is the hardest achievement to unlock (DLC-achievements aside) as it requires no characters take any damage across an entire campaign.

Only 2.5% of players on Steam have this.

The common infected aren’t too much of a nuisance; a quick spray from your weapons will sort these swarms out. The Witches don’t count here, so you can intrude their sob fest and get sliced up without worrying that you’ll lose out on the reward.

However, when Hunters start pouncing from afar, Smokers on the rooftops drag you away while you’re alone, and Boomers rush in for a suicide bomb, you know it’s gonna be a long five-level campaign.
