Subterra is an exciting game on Roblox where players mine and explore, similar to games like Minecraft and Terraria. You dig through different layers of mines to gather valuable resources, improve your tools, and avoid dangerous enemies and falls.
Like other Roblox games, the developers of Subterra share code with players to celebrate achievements, address bugs, and reward the community. These codes are only available for a limited time and can give you extra gold, Chrono shards, keys, and XP boosts to assist you in your mining adventure.
