Big Bad Toy Store has pictures of McFarlane Series 5 figures. This series will include:
Carter (Helmetless)
Ranger Elite
Brute Cheiftain
Skirmishers
Gungnir Spartan
It also seems that this series will include a Weapons pack
While no information has been released regarding any exclusives from this series, there is speculation that the Gungnir may be a Target exclusive, as it follows the same Green/Brown color scheme that the Exclusive Series 3 Military Police figure had.
