Bot Gaiden

Stage completion time affects both boss health and rewards! Every 15 seconds, the Golden Skull will fill up a battery. If you haven't reached the Henchbot (boss) yet, it will be added to his health. After you defeat him, any remaining energy is converted to batteries you can spend on upgrades (which help you go faster)! Not for the faint of heart, Bot Gaiden is all action execution, and speed. Ninja robots Robyu and Bytron race to recover the power skulls that have been stolen by each of Giorqio's 6 Hench-bots. Slicing everything in their path, they must reach their destination quickly. The Hench-bots grow stronger with time and exposure to the skulls.
