Test Room 02 is the fourth room of Fredbear and Friends: Left to Rot. It is a sublocation of Fredbear's Family Diner. It is unlocked immediately after beating Test Room 01 and the active animatronics Rotten Freddy, Rotten Bonnie, Rotten Chica and Rotten Foxy.
Test Room 02 greatly resembles Fazbear's Fright from FNaF 3. The location is full of various restaurant furnishings, such as arcade machines, tables with chairs, and wall decorations. The whole establishment is grim and dreary, as if it has been abandoned for a long time. As the player is brought here after being knocked out by Suit it is not possible to determine the location of Test Room 02 within the grounds of Fredbear's Family Diner.
TacticsThe player's goal is to survive for 6 minutes. The player must keep track of the toxicity meter, which begins at 1% and will cause the player pass out at 100%, resulting in a game over but no jumpscare. The toxicity can be reduced by wearing the gas mask, although the mask's effectiveness is greatly reduced if the ventilation is turned off. The player is not able to interact with the environment while wearing the gas mask.
The player must also defend themselves against the four active animatronics. Rotten Freddy and Rotten Chica will attempt to enter the player's office through the left and right vents respectively, and need to be repelled by using the camera system to turn off the ventilation in the vent that the animatronic is in. Rotten Bonnie will appear in the rear of the office and will move towards the player, at which point he can be repelled by turning on the fan. Rotten Foxy will appear at the end of the hallway and can be repelled by turning the power off in the office. Neglecting any of the animatronics will result in them jumpscaring the player, causing a game over.
- The idea of the toxicity meter is similar to the meter by the same name that was cut content from FNaF 2.
- Test Room 02 is the only room where the player does not receive a call from Phone Guy.
- Test Room 02 is the only room in which the player can be given a game over without a corresponding jumpscare, which happens when the toxicity meter reaches 100%.
