Spike TV has greenlighted Most Lethal, a new unscripted series that should be a suitable companion to the channel’s popular Deadliest Warrior reality series. In Most Lethal, 12 real-life warriors from the top tiers of special operation forces faceoff in a grueling competition to determine who is the fiercest and winner of the “Most Lethal” title. The 10-episode, an authentic look at the covert world, is produced by GRB Entertainment for a summer 2011 premiere on Spike.
