Okay I have found something I have been doing for the past 2 weeks to make the game more fun for myself.
In an attempt to spark a challenge up, here I present to you the "Old Gun Challenge"
Now normally when we have a gun and kill players after a certain number you get a skin for that gun unlocked, there are 4 in all "gold, green, orange, and blue" in that order. However you tend to only use the guns that are the best, like advance rifle vs ak-47. So in an attempt to get those blue skins (last skin to get) I have been using my old crappy guns vs my shiny better ones. You use the most powerful gun till you get a blue skin, then you demote your gun to the lower gun. This slowly raises the challenge in killing players with weaker guns than they are using.
So far I have maxed out my ap pistol, my advance rifle, m16, all in blue. While micro smg and auto-shotgun in orange, with a few other guns in green. Now I am down to now using lower lvl guns to kill players (both high and low) in the game.
Has anyone else tried this challenge before or something like it? If not I suggest you try it, as its really a good handicap for good players and has made the game a blast in my attempt to get all blue skins for lower lvl guns in the game. From using the very best guns in the game to moving down a few pegs. .
