Naked Snake (Metal Gear Solid 3 and Peace Walker) because he has more primitive weapons training and is used to getting around without all this technology. Isaac Clarke from the Dead Space series. He's used to fighting zombies from aliens that are smarter than common Zombies. Artyum from Metro Series. He lives in post apocalyptic Russia and is used to fighting off mutant creatures. Nathan Drake. He's super good at fighting and parkour plus he's really funny and would be a big morale boost. Plus he's pretty much Indiana Jones but younger. [spoiler]I'm thinking about replacing Nathan with Connor from Assassins Creed 3. Not sure which one. [/spoiler]
