- What Could Have Been: The development blog on Platinum's site details a few cool concepts that didn't make it into the game like Sam having a Robot Dog who can launch missiles at enemies and provide mobile cover. Another having a female android partner who could transform and combine with Sam. The former eventually inspired the character of Bladewolf from Metal Gear Rising: Revengeance.
- The robots get mobile cover robots, much like pets. One of them even turns into a boombox.
