The mod replaces the player's model from the motionless silhouette of Gordon to the model of the rebels and gives the opportunity to influence the events in City 17 in the company of friends!

However, Synergy's capabilities don't stop at just one campaign - the mod also offers competitive Team Play and Deathmatch, in which players will take on the roles of the Alliance and the Rebels and go head to head in battle.

To work, you need a license for Half-Life 2 and, if desired, its episodes.
