Wizkids has posted a Print and Play ATA for the X-Force. This can be used in Golden Age and Modern Age Heroclix tourney formats. Get it here.
Led by Wolverine, X-Force battles threats to Mutant safety and security using Black-Ops style methodology and tactics. As you can see, the ATA allows them to slip in and out of the shadows (Hindering Terrain) without penalty to their movement, and at only 4 points per figure, the ATA can fit on a variety of Team configurations in both Golden and Modern Age formats!
