In Prey (2017), players often encounter doors and safes that require high levels of hacking or leverage to unlock early in the game. Fortunately, several strategies can help navigate these challenges effectively. Here’s a comprehensive guide to unlocking these restricted areas while maximizing your gameplay experience:

1. Invest in the Hacking Skill
One of the most impactful choices you can make early in the game is to invest in the Hacking skill. By dedicating four neuromods to upgrade your hacking ability to level 2, you gain access to a multitude of locked safes and doors. This investment can quickly pay off by providing access to valuable items, hidden areas, and progression opportunities that enhance your gameplay.

2. Look for Keycards and Access Codes
Another straightforward method for bypassing locked doors and safes is to find keycards and access codes scattered throughout the game world. Keycards can often be located nearby the locked areas, or by completing specific objectives. For example, the safe located in the Trauma Center can be accessed by a keycard found on the bar’s ground floor. Additionally, codes for safes may be hidden in environmental texts such as emails, documents, or even delivered through context clues scattered within your exploration.

3. Utilize Alternative Entry Points
If you lack the required leverage to force open a door or safe, consider looking for alternative routes or methods to bypass security systems. Hacking computers might allow you to disable alarms or security locks associated with those doors. Always keep an eye out for alternative paths, such as ventilation shafts or rooms adjacent to the locked area, which may provide indirect access to the items you seek.

4. Solve Puzzles for Codes
Certain safes may require you to engage with in-game puzzles or behavior tests to obtain the necessary access codes. For example, the debriefing safe’s code can be acquired by resetting the behavior test and answering specific questions correctly. This mechanic not only adds an engaging layer to unlocking safes but also encourages players to think critically about the information and clues they encounter in the game.

5. Utilize Tools and Equipment
In some instances, formidable enemies or environmental hazards may be stationed near locked areas. To handle these obstacles, utilize tools like the Null Wave Transmitter, which can momentarily disable threats such as Phantoms, granting you the opportunity to access keycards, terminals, or other resources essential for unlocking doors and safes. Remember that managing enemies effectively also contributes to safer exploration of high-value areas.

Conclusion
In summary, early in Prey, successfully unlocking high-level hacking or leverage doors and safes relies primarily on a strategic blend of neuromod investments (particularly in hacking), diligent exploration for keycards and codes, engaging with in-game puzzles, and utilizing tools to clear obstacles. This multifaceted approach aligns seamlessly with the game’s immersive sim design philosophy, emphasizing exploration, skill development, and creative problem-solving on your journey through the Typhon-infested world.
