10 Hardest Video Game Achievements To Unlock

10. The Floor Is Lava - Overwatch

The Achievement: "Get 3 killing blows while wall riding as Lúcio without dying in Quick or Competitive Play."

Overwatch's "The Floor is Lava" achievement is a major pain in the ass for anyone hoping to tackle every 'cheev the game has to offer, largely because Lúcio is one of the game's tougher heroes to master.

Scoring just a single kill as the character is pretty good going, and so racking up three in a single life, all done while wall riding no less, is an absolutely agonising feat.

In addition to the sheer finicky nature of pulling off kills while wall riding, it doesn't help that players have a tendency to steer extra clear of you if they catch wind of what you're doing.

And so, at present the achievement has just 1.26% completion on Xbox and 2.0% on PS4, placing it in the "ultra-rare" category, even if it's still decidedly more do-able than some of the other challenges on this list.
