A well balanced combination of the Valve FPS game: Counter Strike: Global Offensive's weapon case system and skins system, and the weapons of the Valve FPS game: Team Foretess 2. This update to the game has been thought to try to help Team Fortress's trading appeal to some Counter Strike: Global Offensive traders. Adding 3 new maps and finishing a promised one (the snowplow was a lie!) Snowplow, Borneo, Powerhouse, and Suijun this gave Team Fortress 2 players a little something to chew on.
