Sometimes what you need is a little realism in your power fantasy. If you feel that Far Cry 3 is missing some crucial realistic bits, maybe this mod is for you.
Here is the "extremely in-depth Realism Mod" by Ubisoft forum user Panzerjager1943. According to the creator, this mod includes:
-Damage is based on actual weapon terminal ballistics tests
-Sway in sights and aiming are factors of the weapon's weight
-Recoil is a factor related to actual weapon recoil, incorporating bullet weight, powder, velocity, and weight of weapon
-Accuracy is based on actual Minute of Arc extreme spreads for the most realism
-Reload time is 25% slower on Assault Rifles, LMG's, and SMG's
-All weapons have realistic magazine capacities, including with Extended Magazines
-All weapons have vastly more maximum range
-Weapons have proper rates of fire (most especially that PKM.)
-Weapons have a new attachment setup that is a modified version of Leechmonger's attachments mod
You can find it here.
Not sure how to mod Far Cry 3, need a little guidance? The initial post in this thread has some tips and resources you can check out.
And remember: this realism mod will probably pair well with HUD-less Far Cry 3.
