Looks like I already found my next hard-mode weapon in CS:GO.

The R8 Revolver.

That damn this is hard as hell to get any kills with its long recoil time and the level of accuracy needed to kill anyone effectively. I'm forced to lead my corners while keeping the barrel of the gun to eye level to increase my chances of getting head shots while minimizing the need to re-adjust my aim. It seems to have its own quick-fire by slapping the striking bit but it throws off my aim a bit when I do that. If I want to get an accurate first shot I have to pull the trigger but it's a slow animation so every shot has to count. But when the shot is on target, it will hit that player like a truck. Just one or two shots is enough to take out anyone.

But again, it's a tough weapon to use. Some players on voice chat even told me to not use it because it was "too hard to use" but I told them "I'll use it for that very reason then. I like a challenge." They sounded confused after that. XD

It's also my primary weapon with no other secondary fitted.

I'll also keep practicing with the knives to see how to best use them.

Overall, this is the best game to hone in your skills with the keyboard and mouse while waiting for CCP to announce the new game for PC. And if anyone has CS:GO you can friend me on Steam. There is also a Steam Group called DUST Phoenix where we can get together and form squads.
