Pro Counter-Strike: Global Offensive team Fnatic has forfeited a rematch against team LDLC after using a map exploit during the $250,000 DreamHack Winter eSports event.

Fnatic won the match yesterday by boosting one of its players to a ledge that gave him a view and sniping position on almost the entire Overpass map. You can see how players jump on top of one another to reach the spot in the video above posted to YouTube by user David Kallberg. The Fnatic player was essentially standing on an invisible ledge he shouldn’t have been able to reach. While DreamHack’s rules don’t explicitly forbid this, it does count as “pixel-walking,” which was forbidden at DreamHack Summer Summer 2013, according to HLTV.org.

LDLC filed protest, and after taking it into consideration, DreamHack administrators said that the teams will have to replay the match. However, Fnatic has since announced that it’s forfeiting the match.

“With tremendous respect towards the CS:GO community and other teams we have decided to withdraw from the tournament,” the team said on its Facebook page.
