There are 37 known “cheat slots” in Red Dead Redemption 2’s Cheats menu, and IGN discovered half of those before launch day. In Red Dead 2, cheat codes actually exist in the world, and can be found written in a drawer, in a shipwreck, in newspapers, and many other places. Since then, IGN’s Red Dead Redemption 2 Wiki contributors, as well as others on Reddit and elsewhere have contributed to the growing list, doubling IGN’s list of RDR2 cheats to a total of 33. That leaves four cheat codes that are still at large!
