People Are Selling Kills of Marathon’s Hardest Boss on eBay

The Complier is the hardest boss to reach in the extraction shooter Marathon. To even have the chance to fight it, you need to have cleared six vaults—increasingly elaborate puzzle rooms—in the Cryo Archive, Marathon’s end game map. To even get the chance to enter each of those vaults, you need to obtain a key for each. To even get a chance to get one of those keys, you need to kill another set of bosses or find them in dangerous runs of another map. And if you do find a key, or you bring one into Cryo Archive to use, another team of players may simply kill you and take it from you.
Or, you could pay a random guy on eBay to kill the Compiler for you.
