MW3 has a secret neon multiplayer map thanks to G3T_H1GH3R

Continuing its absolutely stellar post-launch performance - arguably the best that Call of Duty has ever seen - Sledgehammer Games is returning the parkour mode to Modern Warfare 3 with a new layout.

Following the success of G3T_H1GH during that 420 era when psychedelics were rife due to Snoop Dogg, Cheech, and Chong's blunt influence over the developers, MW3 is returning to this neon jungle with G3T_H1GH3R.

But that isn't all. There appears to be a secret multiplayer map that only appears for those who defeat the parkour run.

MW3's G3T_H1GH parkour map appears to be getting a core 6v6 variant

Well, there's not much point in having a Ninja Warrior map on Call of Duty if all you win is a sense of satisfaction. I'm afraid we're a lot more entitled than that and feel like the endless grind to get to the top of the G3T_H1GH maps hasn't been rewarded.

But G3T_H1GH3ER looks to change that, as players have found a secret reward that comes for those who reach the top.

As pointed out by "Jaxon" on Twitter, there appears to be an extremely trippy neon multiplayer map which is playable in the 6v6 format. It replicated the digitised look of G3T_H1GH and blends it with the core Call of Duty experience.

The map appears to evolve mid-game, too, which is great news for the anti-camper group. Walls will be erected from the floor to block off lanes of sight, and doors will open to new layers.

According to Call of Duty's own blog, this is just one of "multiple secrets to discover," with more "collectables to find, and traps more dangerous than you might remember."

It's not yet clear how G3T_H1GH's multiplayer map will be added to the game, whether it's exclusive to those who finish the run or a post-run minigame, but the leaked gameplay certainly indicates that it might be one of the most entertaining maps we've ever seen.
