Heya Folks,
Continuing it's support of the newly released rulebook, today Barking Irons brings you a new Optional Special Unit for Alternative Armies' Slaughterloo.
Whilst Elven surgeons piece together their fallen bretheren the Orcs of Albion have a somewhat different approach to getting their injured back onto the battlefield. These rules give Albion players a way to heal their troops in the same vein as the Elf Field Hospital. A seperate and very different unit to the standard Orc Camp Followers they can add an extra dynamic to your games of Slaughterloo.
