How to Play Subject 04: The Investigation

Playing Subject 04 requires careful resource management and quick reflexes. You start in the security office with a limited battery supply. Use your mouse or touchscreen to interact with the retro CRT monitor. Click through the five different camera feeds to search for the hidden confidential documents. Whenever you spot a document on the screen, click it to collect it. However, you must constantly watch out for the monster's approach. When you see the creature reach CAM 1, immediately close your office door to block its attack. Remember that checking the cameras and closing the doors will drain your power much faster. If your electricity reaches zero, the doors will fly open, leaving you completely defenseless against the monster's jumpscare. Balance your time between finding the files and tracking the enemy to secure your victory.

Tips & Tricks for Subject 04: The Investigation

Mastering this scary FNAF fan game means learning how to conserve your energy efficiently. Don't keep the cameras open for too long. Instead, take quick glances to locate the documents and check the monster's position, then immediately lower the monitor. Never leave your office door closed unless the creature is actively standing at CAM 1, as the door drains your battery incredibly fast. Pay close attention to the procedural audio cues, like footsteps, which can warn you when danger is approaching even without the cameras. Stay calm under pressure and manage your power wisely.
