1. Get your own custom game mode of gun game or sharpshooter (not the community)
and load it up in private match
2. Go to Edit Game Options > General Options > Health & Lives

3. Set Health to Double (Or minuscule if you really want to piss people off)

3b. Decrease the Health Regeneration time

4. Start the game and play right through to the end

5. Switch Lobby to Wager Match

6. Search for Gun Game and hope for host (auto host glitch would piss people off even more )

7. Enjoy: Everyone in the Game can take a full clip from the .44 but will regenerate in the time it takes to reload

this should work just the same as the one in the chamber unlimited life glitch

If this helped +rep and thank topic
