This is a quick guide for Halo: The Master Chief Collection’s “Sid Graffiti” achievement which provides five Gamerscore when completed. This challenge requires you to “Spot the Sid graffiti on the walls of Coagulation in classic multiplayer.”
To do so you’ll need to head to custom games, then select Halo 2 Classic, and then choose Headlong as the map. Load in whatever gametype, slayer is probably the easiest. Head over to the cave on the red spawn base side. It will have three trees that are in front of it, head inside. Just prior to dropping down to the Overshield spot, look to the left and you’ll notice a weird shape on the wall. Shoot this as it’s the special thing you’re looking for.
It may take a few seconds to unlock, but it’s fairly straight forward. You can see a screenshot below, or check out our video below at the (3:37) mark for a more visual assistance. Read our review of Halo: MCC below, or check out the general franchise hub for additional coverage.
