Protocol is an RPG puzzle game for the PlayStation Vita and, later, the Nintendo Chrome. The game centres around twenty captives with the objective to escape their prison and an artificial intelligence program that is hunting them down. The game was heavily inspired by the Zero Escape series and was announced during the Fantendo Holiday Showcase 2014. The game spawned a spin-off title named me and my shadow.
Protocol is a puzzle game with RPG-elements that take place within Cove's mind. The characters are trapped within an abandoned laboratory, with puzzles that must be solved in order to open more areas. These puzzles involve various items scattered throughout the room, that must be obtained to activate certain elements of the puzzle.
Most story sections of the game take place in a visual novel-esque gameplay section, that focuses on character interactions and choices that initiate which ending is obtained. There are twelve endings in total, with one "bad" ending, one "true" ending and ten that must be obtained to activate the true end.
“Why does my mouth taste like.... eggplant?”
Cove wakes up in a small silver box, alongside nine other people. The left wall, a window, shows ten others. With a single exit being the ceiling hatch that opens on both sides of the glass. The group decide to first escape the room, before introducing themselves and attempt to figure out why they're here. Once they escape their first prison, the group, in a state of confusion, meets their captor's avatar: Crux.
“Welcome to my glorious little kingdom. If you want out, there are only two exits accessed through dire trials. Either death at the hands of me, or death at your own hands!”
The Silver Room is the first puzzle in the game. The puzzle contains four sub-puzzles that must be completed to open the exit. The two sets of prisoners must work together on two sides of a glass pane to complete the puzzles, entering codes into six machines that are linked to each other. The first and second codes are carved into the ground of both rooms, though must be looked at from opposite angles to find the passwords for two of the consoles: 6686068 for the console in Cove's room, and 8909899 for the other.
The third and fourth clues are painted on the walls of both sides and must be unscrambled by looking through a slit in the glass wall.: 1357975 and 2468013.
The fifth and sixth clues, the final ones, are located within the two other clues. Cove, trying to solve the final puzzle, tries various combinations of the numbers given before ending up with the final two passwords, which he got from combining the two, alternating between the two sets to get the two passwords: 6387078 and 1959995.
After entering the three passwords, the two groups exit into a larger room, where they must line themselves up in their numerical order. They must do so with a tattoo of their number in roman numerals. Doing so finally allows them to escape, and they are greeted by Crux.
