    Marathon Man Egg: This Easter Egg is hard to miss, as it doesn’t require anything to trigger it. In fact, all you need to do is watch the cutscene at the start of Gravemind on Legendary without skipping it, in CLASSIC mode and this will unlock. There's another easter egg guy to the right in Anniversary mode, but the achievement will only unlock of you witness the Marathon Man in Classic mode during the cutscene.
