Depending on what sort of roleplay genre and you're going for, you can sure as hell bet that GUNS are going to come in to play at some point. You should already be aware of how to control objects within a scene, but gun fights often have some special mechanics of their own. Things to consider: Guns need to be RELOADED. Your average six-shooter has six bullets. Some guns have up to 30 rounds or more. Some guns use bullets that have to be loaded individually and some guns have clips or magazines. Know what kind of gun your character is using, so when you're shooting down bad guys, you know when your character has to pause and reload. Ammunition isn't limitless! A character is only going to be able to carry so much on them, even if they are a super awesome soldier. Again, know your gun! Distance a gun can fire, how it tears the body, ways you need to hold and shoot. A hand pistol is different from a shotgun, which is different from a machine gun! Is this gun AVAILABLE to your character? Are they able to purchase and own it legally? Do they have it because they are a cop or a soldier? If they were caught with that gun, would they go to jail? In sci-fi plots, you have the ability to get CREATIVE with the way a gun works! But the above things still apply. A single gun isn't likely to have limitless fires, even if it's laser powered. Does your gun need recharging? New ammunition? What is the damage it does to the body when it hits? Is it a civilian or military weapon? Black market? When you get shot it's going to HURT. Even if you're a turbo badass. Make sure you take the hit and try to reflect how it's affecting your character, be it through pain, bloodless, loss of function because of the wound, etc. How does your character feel about using guns? Do they have problems with it? Are they used to it because of their job? Have they ever shot a gun before? Have they ever shot some ONE? In this exercise, you're keeping in mind how to accurately depict using a gun along with how your character handles using the weapon! Write a quick gun fight scene between your character and someone else of your choosing. Try to hit on some of the points here in this exercise as your describe the fight!
