# The Scrapyard Once a player has installed 3 permanent upgrades on their Tier 1 mining rig, the Scrapyard will offer them $ASTRO for those upgrades. Trading in three upgrades from a Tier 1 mining rig will net the player 440,000 $ASTRO while a fully upgraded Tier 3 mining rig will reward the player with 1,716,000 $ASTRO. After a mining rig has hit Tier 1 + 3 upgrades, it can be sold back at any time with any amount of upgrades. Each upgrade adds additional value to the sale. Whenever upgardes are sold, the mining rig is reset to a base Tier 1 rig. NOTE: Mining rigs must be unstaked from before the scrapyard can strip off the upgrades. After the upgrades are sold, the rig must be staked in the docking bay again to start mining. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
