You can always try bringing characters from some shooter, those npc guys are trained like Rambo, or maybe mmorpg games have characters and items that any of us readers would love to see, like World of Warcraft, or more simply Warcraft 3 because here You will find the Paladins with the ability to resurrect multiples, if ever someone dies, and don't forget that all the characters are like Super Soldiers.
