Undertale RP: Mess Timeline is a Roblox morph roleplay game from the creator nanquadii, set in the world of Undertale. You morph into and roleplay any Undertale character you like, explore the map, and hunt down hidden chests for Points that unlock new characters and skins. You can also collect badges around the map for free characters and buy skill attacks from three shops in Snowdin, though those attacks only hit enemies, so the game has no PVP.

How to Play Undertale RP: Mess Timeline
- Load in and morph into the Undertale character you want to roleplay, since the game is built around playing your favourite character.
- Explore the map and open every chest you find, since chests are how you earn the Points that unlock more characters and skins.
- Collect the badges scattered around the game, since each badge unlocks a free character you can play as.
- Visit the three shops in Snowdin to buy skill attacks, which let your character fight the enemies in the world.
- Redeem the latest codes for free Points, so you can unlock your favourite characters faster.
Undertale RP: Mess Timeline Gameplay and Strategy
Undertale RP: Mess Timeline is built around character roleplay and exploration rather than a score or a competitive grind. Every server is a shared Undertale world where players morph into the cast and act out scenes together, drawing on the characters and areas fans of Undertale know, like Snowdin. Picking a character and committing to the roleplay is the heart of it, so the reward is a good scene rather than a number going up.
Unlocking characters and skins is the main thing to chase. You earn Points by finding chests as you explore, then spend them to unlock your favourites, while badges scattered around the map unlock extra characters for free. Codes hand out free Points on top of that, so redeeming the active ones is the quickest way to fill out your roster without grinding chests for hours.
The combat side is light and cooperative. The skill attacks you buy from the three Snowdin shops only damage enemies, not other players, so there is no PVP and nothing to lose to other people. Servers hold up to 30 players, nanquadii keeps adding new characters and skins in updates, and the game shuts its servers down whenever a new update goes live, so the world keeps growing over time.
Tips for New Undertale RP: Mess Timeline Players
- Morph into a character you actually want to roleplay, since the fun comes from playing your favourite rather than rushing to unlock everything.
- Explore the whole map and open every chest, since chests are your main source of the Points that unlock characters and skins.
- Hunt down the badges around the game, since each one unlocks a free character without spending any Points.
- Redeem the latest codes early for free Points, since they give you a head start on unlocking the characters you want.
- Visit the Snowdin shops for skill attacks so your character can actually fight the enemies in the world.
