5Aces joined the Gamesession Hannover 2015 Winter with a random team. Two members of 5Aces, one former member and two standins plus the management took the chance to get to know each other and discuss the future of the roster. The team managed to win their first two group matches before the streak was stopped by server issues due to a Valve update that was released hours before. Several players had completed the update, but the servers of the Gamesession Hannover were not updated.
