Bank

The Bank (or Buffalo Bank) is a limited storage vessel where all Kill Coins are stored after tower runs and raids. The Bank, like the SPLithium Tank, has a default capacity of 50,000. Capacity can be increased by purchasing upgrades with SPLithium in the Waiting Room > Defense Equipment menu at the Tokyo Death Metro Front.

In TDM raids, the Bank is a destructible item that drops Kill Coins - up to 10% of its current balance. Upgrading the Bank will increase its HP and make it harder for enemy raiders to destroy within the time limit.
