Are you sure you haven't been playing yourself? Look at the sheer amounts of guns that still use the same mechanics as modem rifles."Iridium-core rounds?" One of the most common modifications? Iridium is a solid, if you haven't ever took your high school chemistry. Sure, there are fusion rifles. But look... Scout Rifles, Auto Rifles, Pulse Rifles, etc. Where's your common sense? Don't refer to the minority of the weapons, such as a Fusion Rifle. Hell, even Fusion Rifles use the IRIDIUM-CORE ROUND modification LOL. That doesn't even make any sense.
