Master Override locks and doors are areas and items you can access after obtaining the Master Override Security Clearance in the Dead Space Remake (2023). Read on for a complete list of all Master Override locks in the game, including info on how to get to each one and the rewards for looting them.

How to Unlock Master Override Security Clearance

Finish the You Are Not Authorized Side Mission

To unlock Master Override locks and doors, you will first need to obtain the Master Override Security Clearnace. This can be done by acquiring the different officer RIGs scattered all over the Ishimura and completing the You Are Not Authorized side mission.

Note: This side mission cannot be fully completed until Chapter 10. This means you will have to open a lot of these locks before hitting the point of no return in Chapter 11 so as not to miss any loot.
