With Path to Oblivion (Part 4), we start with a companion that we met up with in Part 3. While this adds a level of support, it also adds another level of complexity, since we are now tasked with keeping Sgt. Kelly alive or else the mission ends. Players will be given 3 lives. Sgt Kelly only has one. Playing as a single player, I found it pretty difficult to keep Sgt. Kelly on his feet during the 3rd (and I think final) trial in this map. I reckon it's much easier with more players. The map itself is a series of Hell modules stocked with ammo and weapons. There are 3 trials to play through before moving forward. The map is supported by a story line and accompanying dialogue by Sgt. Kelly.
