Mega-creeps comeback

The objective of Dota 2 is to destroy the opposing team's ancient, which requires killing the four tiers of towers first. Before that, a team can upgrade their creeps to mega creeps by killing buildings known as barracks. It is tough to win the game once you're fighting against mega creeps, especially going against the best teams in the world. Imagine an NFL team is down by three touchdowns with five minutes to go; that would be a similar scenario.

Before the International 6, there had never been any comeback wins against mega creeps. In a 75-minute affair, Evil Geniuses, EG, achieved that feat against EHOME in game 1 of the upper bracket round 2. EHOME was up 20k gold at one point before EG slowly chipped away the lead and came back by using dagons. There have been a few more comebacks against mega creeps since then, but many people consider this game one of the best dota games ever.
