Subterra drops players into a 2.5D mining world packed with monsters, crafting recipes, and buried loot. Polyworks Studio hands out redeemable codes tied to community milestones and updates, giving miners a shortcut to Chrono Shards, gold, keys, and temporary XP boosts.

How to redeem codes in Subterra
Code redemption happens through an NPC called Chrysos, stationed near the spawn gate. The process only takes a few seconds once you’re standing in the right spot.
A successful redemption shows a confirmation message on screen and adds the reward directly to your inventory or currency total. If nothing appears after hitting Claim Code, double-check the spelling before trying again.

New codes tend to arrive alongside major patches, member-count milestones, and other community events, so it’s worth checking back on this page periodically. You can also join the official Subterra Discord server or drop into the Subterra experience on Roblox directly to catch announcements as they happen.
