ChemPass is a battlepass-like tiered reward system. Complete challenges ingame to tier-up your ChemPass and earn rewards. Every player gets free access to the basic pass, which grants occassional rewards. If you already have a ChemPass, upgrading to Premium will grant you access to the 150 Premium-tier rewards alongside the free-tier rewards on every ChemPass tier-up. If you've already tiered-up your ChemPass, you can claim your missed Premium rewards in the rewards section of /chempass. 

Premium rewards include extra cosmetic chat tags, keys, exclusive pets, packages from our store, and other exclusive items. See the Premium rewards by doing /chempass ingame.

If you don't already have a freeChemPass, claim yours in-game with /chempass. 

* This Premium upgrade will last until the end of the ChemPass, on September 22 2026. Upgrading to the Premium ChemPass will grant access to 150 tiers of Premium ChemPass rewards, which can be achieved through tiering-up your ChemPass until the end of the season, on September 22 2026.

If you choose to also purchase ChemPass tiers:

Purchasing any number of ChemPass tiers voids your eligibility to the Tier 150 ChemPass Completion Rewards (your head in the museum, the exclusive completion tag) and to appear on the ChemPass leaderboard. In other words, only players who complete the ChemPass by earning all of their EXP "manually" by completing quests in-game are eligible for the Tier 150 rewards and ChemPass completion recognition.
