The conveniently named piece of Saints Row IV DLC, the GAT V Pack, is currently available for free on Steam. This offer is only available today, and ends at 12:01AM Pacific.
Included in the pack will be a bunch of clothing related to Johnny Gat, a knife gun, and other assorted goods. Considering Volition’s M.O., this looks to be a not-so-subtle poke at the recent release of GTA V.
