Gears of War tells the story of Marcus Fenix and his fight for humanity’s survival against the relentless Locust. The game is full to the brim of heroism, tragedy, shotguns to the face, and chainsaws to the neck. Humanity’s death toll is high, but you can pay your respects to those they’ve lost by picking up mementos from fallen comrades, in the form of COG tags.

The tags can usually be found near a Crimson Omen, the Gears of War logo. Three achievements are available for collecting the tags, awarded after finding 11, 22, and 33 tags. They do not have to be collected in one playthrough, and the achievements are available on any difficulty. Note that only 30 of the COG tags are numbered. The PC version added additional levels in Act 5 with three extra tags. If you’re playing the original version of the game on Xbox 360 then there will only be 30, and the requirements for the achievement are lowered accordingly. The Ultimate Edition has all 33 tags.
