The "Ape Escape" series is notable for its radical departure from the tried-and-true control method in many other games. It was the first PlayStation game to require the use of a DualShock or Dual Analog controller; the left stick moves the character while the right operates whatever gadget the character has its possession. Again, unlike many games which use to jump, both the R1 and R2 buttons are used, while the 'shape' buttons are used to cycle through the available items in the inventory.
