PROTOCOL
A downloadable mod
The club meeting ends like any other night. You say goodbye, grab your bag, and head for the door.
Except the door won't open.
You wake up in the same clubroom — except now it's the middle of the night, the building feels wrong, and none of the exits work. Something is watching, and it wants you to follow a set of rules before it lets you leave.
Protocol is a horror mod for Doki Doki Literature Club. Help each of the girls, solve their puzzles, and try to find your way out — if there's really a way out at all.
Features:
1) Four distinct character routes, each with unique puzzles and minigames
2) Multiple hidden codes, ciphers, and secrets to uncover
3) Two different endings
4) An original soundtrack
5) Estimated playtime: 45 min - 2 hours (depends on how lucky and smart you are).
This mod contains loud sounds, jumpscares, flashing/glitching visuals, and disturbing imagery. I recommend playing with headphones, in a dark room, and with your screen brightness turned up since this mod leans into a lot of night-time visuals.
GOOD LUCK!
