Some luck will be required. Have at least 10,000 in the bank to attempt this multiple times. About 1,000 will be required per run. Have Max Bullet Magnet and Max Discount. Also consider getting Max Life Insurance if needed. Max Carry and Backpack are also useful. Reloader is the best item that can be used; purchase a lot of bullets. Also consider keeping a Reloader on Bank in a previous run before speedrunning. Always keep Reloader equipped and six red potions in your Backpack to restore your health as needed.
