How to redeem Subterra codes
What is Subterra?
Subterra is a Roblox mining game from Polyworks Studio that draws on the design of classic exploration titles. Players descend through layered underground caves, collecting ore and resources, discovering buried structures with lootable chests, and fighting the monsters that guard deeper zones. Upgrading your pickaxe and backpack determines how far you can venture, while a crafting system lets you forge weapons — from swords to bows — using recipes found during exploration. The deeper the layer, the richer the rewards and the harder the challenge.
Where to find new Subterra codes
Polyworks Studio releases new codes when the game clears community milestones — things like member counts, likes, and total visits. The official Subterra Discord server is where announcements tend to land first, so keeping an eye on the announcements channel is a reliable way to catch drops early. We check for new codes regularly and update the working and expired lists as they change, so bookmarking this page keeps you covered without the manual hunting.
