Restore Health + Vehicle Repair
This one might come in handy and it actually doesn’t require you to enter any codes and/or lose out on achievements. Basically, if you have your health low, you can spawn to another character, then spawn back and your health will be restored. The same goes for a vehicle you were driving in that got wasted during a high speed rampage. Just spawn to another character, then spawn back and it will be restored to tip top shape.
