That would be fantastic!
I was thinking Eli would have duel pistols of some sort, something quick to fire and reload. Easy to maintain and care for; while Max would have a sort of Sniper Rifle(Maybe an A.W.P? I don't even know if that's a real gun but it's in Trouble in Terrorist town and CS:go) and maybe a slightly larger handgun than Eli's, not as rapid fire but good for someone who has good accuracy.
