  • Hello! Today I updated Chain Letter's Steam page. - 30 December 2025

    First, I replaced the game description and capsule art.

  • Intro and Character Art Rework in Progress! - 30 July 2025

We’d truly appreciate your support and wishlist in the meantime.While you’re here, take a peek at the reworked character art in progress! :) The cold and snappy Jamba has become even more icy. ❄️ The gloomy, melancholic Jupi... might have gotten a bit brighter?And main character Mongsil is now even more simply cheerful!!and additional expressions.....

Short description

《Chain Letter》 is a grid-based control roguelite defense game. Unlock and combine friend skills with unique commands to build your own setup and hold back the oncoming demons.

About this game

《Chain Letter》 is a grid-based control roguelite defense game. Combine friend skills to complete your own skill build, and hold back waves of demons within a fixed grid. Clear 4 stages and unlock 31 friend skills to form your own party—then dive into this chaotic battle! Key Features Grid-based control: Thrilling combat where dodging and execution decide victory Addictive hands-on feel : The more you master it, the more insanely satisfying it gets Friend skill combos: Unlock 31 skills and craft your own build Short and fast runs : Optimized for repeat play with a brisk pace 4 stages: Tougher enemies and new patterns as you progress Sometimes powerful foes will appear—sometimes overwhelming bullet storms will rain down. In the chaos, you must move quickly within the grid and use your skills to hold the line. Each “friend skill” has its own unique command, and the more you get used to the controls, the more satisfying it feels. Gather different types of skills (summons, rapid strikes, AoE, buffs) create your own combinations, and even if you fail, try again and grow stronger. Defeat the demons that keep surging in, all the way to the end! Story in the Game You play as the protagonist “Mongsil,” caught in a mysterious incident, and must escape a world that repeats for unknown reasons. In this hellish world, a magical letter is the key element. The letter is used to unlock friends sealed by a curse, or to strengthen skills. Can you unlock every friend and escape this world? Deliver the letter, unlock and upgrade your friends, and push toward the exit from hell!

Price History Overview

USD uses SteamPulse's own locally recorded daily store snapshots, so this overview reflects the exact regional price history that SteamPulse has captured for this currency.

Coverage And Tracking Window

  • Snapshots: 1
  • Coverage: Sep 23, 2026 to Sep 23, 2026
  • Lowest observed: $0.00
  • Highest observed: $0.00

Chain Letter's USD price history spans from Sep 23, 2026 to Sep 23, 2026, with 1 recorded snapshot across 1 calendar day. Each row records the available final price, listed base price, and discount metadata for that observation. Within this coverage the lowest recorded price is $0.00, the highest is $0.00, and the first visible tracked price is $0.00. These comparisons apply only to the snapshots SteamPulse holds; missing observations can contain changes that are not represented here.

For USD, SteamPulse uses locally captured regional storefront snapshots and does not reconstruct older prices with exchange-rate conversion. The chart and table show the values recorded for this exact currency from the stated coverage start. Additional snapshots extend that record, but they do not fill unobserved days or prove what the storefront displayed between observations.

Discount Windows And Sale Timing

  • Discount windows: 0
  • Discounted days: 0 days
  • Deepest markdown: No discount tracked
  • Latest sale window: No sale window tracked

Chain Letter's tracked USD rows do not contain a discount window. This means no available snapshot in the stated coverage has usable discount metadata; it does not prove that the game was never discounted. Missing snapshots or archived rows without complete metadata can hide a sale, so SteamPulse does not infer pricing strategy from this absence.

If a later snapshot includes discount metadata, it will appear here with its recorded depth, price, date, and sale name when available. Until then, this section should be read only as a description of the available rows, not as evidence about the publisher's promotion policy.

Observed Price Changes And Stable Runs

  • Observed price drops: 0
  • Observed price rises: 0
  • Longest stable run: 1 day of uninterrupted daily tracking
  • Current run: 1 day of uninterrupted daily tracking

Outside rows carrying discount metadata, the tracked price has not recorded a separate price rise or drop yet. That means the observed undiscounted level has stayed stable across the snapshots SteamPulse currently holds. This is a statement about the recorded coverage only; it does not prove that an older or missing price change never happened.

The longest unchanged price stretch in the current record lasts 1 day of uninterrupted daily tracking at $0.00, from Sep 23, 2026 through Sep 23, 2026. Among rows without discount metadata, the longest unchanged run lasts 1 day of uninterrupted daily tracking at $0.00. The latest run records $0.00 for 1 day of uninterrupted daily tracking as the same recorded undiscounted price. Run lengths describe consecutive stored observations only and do not establish that a price is permanent.

Latest Snapshot And Sales Context

  • Current price: $0.00
  • Current list price: $0.00
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records Chain Letter at $0.00 in USD, with no active discount metadata. Across the available history SteamPulse has recorded 1 distinct final price in this currency. This supports comparisons with the lowest, highest, and most common values present in the retained record, subject to the stated coverage limits.

The live sales view and Steam sales record provide calendar context for these dates. A date overlap can be compared with a named Steam event, but it does not prove why a publisher changed a price. As new daily rows arrive, this overview recalculates its observed prices, discount windows, and run lengths automatically.
