Trapped Within

Trapped Within is the main game mode available from the start of FNaW: Trapped Within.

Premise
Trapped Within is the primary mode in the game. The gameplay style is heavily reminiscent of Five Nights at Wario's 3. The player must survive in the house for 5 nights, hiding in a different room each night, forcing them to face a new group of enemies and learn new mechanics. Many rooms are similar to FNaW 3, having either 2 characters with the same mechanic, 2 that act the same and 1 that has a different gimmick, and other combinations.

The story of the mode alters the story of FNaW 3, where before the spirits were sent back in time by Rosalina, she was stabbed by Richard and possessed. The player must find parts around the house to repair a Time Machine that allows Rosalina to be saved, and allows the spirits to be sent back in time.

Standard Mode
In this mode, the player goes through the standard 5 night progression. Each night, besides Night 1 and 5, the player chooses from 2 rooms to hide in, which change depending on the room chosen in Night 2. Each room offers new characters and mechanics to learn.

Certain rooms have pieces to be found that allows the player to active the Good Ending upon finding all 4, and using it in the Cellar. If the player completes the Cellar, they can instead activate the Bad Ending. Both endings are required for progression.

The progress of Standard Mode can be reset from the top of the menu, allowing the player to go back to Night 1. This cannot be undone.

Single Room Mode
Single Room Mode is a mode in the unlockable Custom Night, which is unlocked after completing the Bad Ending. This allows the player to select and play any room in the game whenever they want. They are also able to choose the AI difficulty of the characters, which can be set from 1 to 5.

Good Ending pieces are not able to be picked up in Custom Night, however, Easter Eggs can be found in Custom Night.

All-Out Mode
All-Out Mode is another mode available in the Custom Night, similar to FNaW 3. In this mode, the player takes on all rooms in the game on their maximum difficulty. This is one of the hardest modes in the game.

The player's progress will save if they die or quit the game during All-Out Mode.

Trivia
