* WhatCouldHaveBeen: The development blog on Platinum's site details a few cool concepts that didn't make it into the game like Sam having a RobotDog [[CoolPet who can launch missiles at enemies and provide mobile cover]]. Another having a female android partner who could [[TransformingMecha transform]] and [[CombiningMecha combine]] with Sam. The former eventually inspired the character of Bladewolf from ''MetalGearRisingRevengeance''.
** The robots get mobile cover robots, much like pets. One of them even turns into a boombox.
