My belief in the perfect NON-VIP hack is...
1. Full Bright
2. No Fog
3. No Recoil
4. No Spread - Highly suggest only use this with Sniper Rifles from a distance. If your using close up people will notice.
5. Glitch Key = Hold G and Walk Threw Anything - Hopefully people are careful with this.
6. Pickup Hack = Hit C or Control and it will bring all Weapons - Supply Crates laying around on the field to you.
Why did I pick these? Because they are really hard to even notice. Well except the Glitch Key if you are just really stupid with it.
