The Red Dead Redemption 1 mod removes all doors in the game that are not part of the built-in wall design. This allows players to explore some interiors that are usually only accessible during missions or are locked until a certain point in the game. However, it is worth considering that some interiors have invisible barriers that will not allow you to enter. You may also encounter structures without interiors and various glitches when attempting to enter buildings that were not originally intended to be visited. Installation:
