Subterra blends the mining loop of Minecraft with the crafting and combat of Terraria, sending players underground to dig, upgrade gear, and fight off monsters. Codes from developer Polyworks Studio hand out Chrono Shards, gold, and temporary XP boosts that speed up that progress without extra grinding.

How to redeem codes in Subterra
Code redemption in Subterra happens through an in-world NPC rather than a menu, so you’ll need to be inside the game to claim rewards.

New Subterra codes tend to arrive around subscriber milestones, visit counts, and patch releases, so the list above changes often.
