Kill Coins are the currency in the Tower of Barbs in Let It Die. They are used to purchase a wide variety of goods and services, including weapons and armour at Choku-Funsha, or use of the regular elevator. Kill Coins are acquired by killing enemies, finding them in lockboxes, or purchasing them with real-world money. Kill Coins appear to be large, gold-coloured coins, similar to Canadian loonies or Japanese 500-yen pieces.
