Miller,
I don't think there are hacks for such things, but there are legal settings and tricks. See below.
To Move Fast:Step 1
Equip the "Extreme Conditioning" perk to your character in the "Create a Class" menu in "Multiplayer." This will allow you to sprint for a longer period of time.
Step 2
Equip a light weapon to your class such as an SMG or a shotgun. If you aren't sure how light a weapon is, check the mobility level of the weapon in the "Create a Class" section.
Step 3
Run long distances with your pistol equipped instead of your main weapon. You run faster with a pistol equipped than your regular weapon, regardless of how mobile it is.
To Switch Weapons/Reload Fast:1. Sleight of Hand perk....fast reload
2. The Abort Reload Process Script (Reload Cancel)
The Problem
If you are like me and have a habit of always topping-up your magazine right after you have fired off a few of bursts, you undoubtedly have experienced the situation where an opponent catches wide open in mid-reload.
Sure, you try to stop the re-load process or you try to swap out your empty weapon for your backup as fast as possible, usually to no avail: you're fragged and your empty-chambered weapon lies useless next to your limp, bloody avatar.
The Solution
Binding the following script to one of your keys:
bind E "weapnext; wait 2; weapnext"
Assuming you still have rounds in your magazine, or at least a chambered round, if you are mid-reload - the process is immediately interrupted and your gun is back in business, ready to fire.
The delta-time between gun "reload" to gun "ready" is nearly instantaneous and your attacker will soon find him/herself the attackee.
