Update: Checked for new Subterra codes on June 01, 2026.
Subterra is a 2.5D underground mining adventure on Roblox, drawing heavy inspiration from Terraria and Minecraft. Players descend through layered cave systems, harvest rare ores, battle monsters, and upgrade their gear as they push deeper underground. Developer Polyworks Studio hands out codes at community milestones and major update launches, offering free chrono shards, potions, XP multipliers, TNT blocks, and gold to keep players well-stocked on their way down.
