This achievement requires that you win a Manhunt game scoring every point for your team. Manhunt mode consists of two teams fighting for control of a single flag in the middle of the map. Once a player grabs a flag, he starts racking up score for his team, one point for every 5 seconds carrying the flag.. The other team tries to kill them and take the flag. So essentially you must be only one on your team to hold the flag from your team in a winning match. You need at least one other player to start a match. Create a custom Manhunt match with a Time Limit set to the minimum (5 minutes). The player going for the achievement should grab the flag from its starting position and hold it until time expires.
