From publisher blurb:
The size of a grizzly bear, the vaguely humanoid Spikeback is a genetically engineered bio-weapon of old -- which has evolved.
Now, exhibiting an occasional cybernetic implant or mutation, they move about the wastes of The Mutant Epoch in packs, and gorge on the flesh of other living things. Bad tempered, ravenous and cruel, this freaky creature of the apocalypse is our third nasty in this series.
Although crafted for the Outland System Game Mechanic, a GM can easily modify the Spikeback’s stats over into most any post-apocalyptic game system.
