Once Human Reroll Guide - Is It Worth It & How To (2026)
An open-world survival game with a strange, monster-filled world — redeem codes for free Starchrom.
Open-world gacha games have longer tutorials, so rerolling is slower — but a strong first limited character carries you through the whole early game, so many players still do it.
How to reroll in Once Human
- Use a guest account or a new email so you can reset fast without losing your main.
- Rush the prologue to the first banner, skipping cutscenes, and grab starter rewards plus active codes.
- Pull on the limited character banner you are targeting.
- No luck? Reset the data or start a new account and repeat. Got it? Bind the account immediately.
What to reroll for in Once Human
Aim for a top-tier limited main DPS (or a universal support) you can center a team on for months.
How long does a Once Human reroll take?
Expect 15-30 minutes per reroll because of the tutorial. Because it is slow, many players reroll only for a must-have unit.
Redeem active codes on every fresh account for extra pulls. Once Human has 3 working codes right now. See the Once Human codes list.
