Call of Duty: Black Ops III has a Cheat Menu where players can enter the CHEATS and make the game much easier. The discovery was made a user on Reddit Ron_Scottznbrgr. There are two button combinations to access Cheat Menu in Call of Duty: Black Ops III: " Hold R2/RT, and hit Square/X, then Triangle/Y, OR Hit Square/X, then Triangle/Y, then press R2/RT. No need to hold all of the shoulder buttons." No details yet on how to access Call of Duty: Black Ops III Cheat Menu on PC (I will update this post as soon as I get to hear something on it).
There is still no confirmation on whether or not using Cheats in Call of Duty: Black Ops III disables Achievements/Trophies. Ron_Scottznbrgr didn't receive any warning trophies/achievements disable after he entered a cheat code.
Also, there are absolutely no confirmation, noises, or any sort of visual/auditory feedback that you entered a cheat correctly. This is annoying considering the fact that players have entered a bunch of codes already, and would never know.
Here is the full list of Working Call of Duty: Black Ops III Cheat Codes. Note: We will keep updating this post with new codes.
