At a glance

A small team inside a large publisher launched on weeks of runway, not months.

ReLU Games used FirstLook to validate demand, run multi-region playtests, distribute Steam keys, and stand up a Discord community, without building any of it themselves.

1M+ Copies sold post-launch

The problem

A studio inside a publisher, with a launch window and almost no publishing-side bandwidth.

ReLU Games — KRAFTON's internal label — was readying MIMESIS, a co-op horror title, for Early Access on October 27. The project was greenlit with a launch slot, but without the dedicated marketing, QA, and community-ops resources a typical KRAFTON release would receive. One primary operator — Junhyung — needed to run the entire pre-launch program day-to-day.

Six things had to ship before launch day.

  1. 1

    Validate real player demand

    ahead of October 27. Structured signal a launch decision could rest on, not just awareness.

  2. 2

    Run multi-region playtests

    across Korea, Japan, English-speaking, Brazilian, and Russian audiences, on a branded ReLU domain, with Korean-privacy-compliant sign-up.

  3. 3

    Distribute Steam keys at scale

    across the full tester cohort, staged so keys could be pre-assigned but hidden until a single simultaneous reveal moment.

  4. 4

    Stand up a Discord community

    with verified onboarding and automated role assignments, without building any of that tooling in-house.

  5. 5

    Track post-launch sentiment

    across Steam reviews and Discord conversations to flag technical issues and confirm what was resonating.

  6. 6

    Operate the entire program

    on a timeline measured in weeks, with one primary operator running it day-to-day.

The solution One platform, six workstreams

A dedicated MIMESIS instance, live in days, covering the surface KRAFTON would have built itself.

01 · Testing surface

Branded domain & regional flows

Custom playtest.relu.games, global English primary, Japan / Brazil / Korea / Russia setup, age-gated 18+ eligibility, and on-demand template duplicates.

5 regions Custom domain 18+ gate
02 · Distribution

Steam keys, hidden until reveal

Steam App ID + Web API configured, wishlist CTA on the waitlist, ownership and playtime tracking, and the full tester cohort pre-loaded so every key was revealed at the same instant, at 4 PM KST.

Staged drop Wishlist + ownership tracking
03 · Community

Automated Discord onboarding

Native Discord auth, automatic role assignment by cohort, auto-join into the official server, and onboarding gating tied directly into key distribution. Studio Ops on standby through key-drop day.

Auto-roles Verified join
04 · Localization

Korean & Japanese flows, KR-compliant

Korean primary plus Japanese flow with localized copy. Custom required-checkbox clickthrough agreement to satisfy Korean privacy-policy requirements inside the sign-up form.

KR · JP Privacy compliant
05 · Tester ops

One source of truth

Player CRM with search, segment, export, and login-as-player. Roles & invites for beta cohorts and friends-of-testers. Refer-a-Friend in the waitlist flow; each invitee given 3 direct invites.

CRM Referrals Cohorts
+ Hands-on

Enterprise support throughout

Pragma's Studio Ops embedded with the ReLU team, including unblocking a Discord-API incident in real time on key-drop day. New flow templates spun up on demand as plans evolved.

It's hard to imagine what would have happened without FirstLook. Their fast and efficient user testing ultimately led to the decision to move forward with the project's release, and the game went on to achieve over one million copies sold.
