Say I'm out in our base and I'm looking to pick off some people. Should I use the Rifle, or the SMG? I'm a decent sniper with the Rifle, but I guess using the SMG to get at least a kill in each time would work.
Let's go with charging. Should I use the SMG, or the Shotgun? I know the SMG is rapid-fire and can be used easily, but the shotgun can destroy blocks and deal a lot of damage quickly.
Finally, I'll do sneaking.
When I'm trying to sneak around to the base of the other team, do I take a SMG, Rifle or a Shotgun? SMG is particularly useful, since it can take down enemies fast. Rifle could be good if you spot enemies farther out, and the Shotgun could be to penetrate and damage at the same time. Post what you think.
