Space Ship: Operation Shutdown -Mockup

This is a mockup of an extreme space ship exploration game where you play as an astronaut that just crashed his space ship, He finds an abandon space shuttle that looks like it's from the future , he decides to go into it to see if maybe he could turn it on. This becomes a huge exploration game where you find friendly robots along the way to guide you, while you also have to defeat not so friendly robots. I'm thinking that this would be a fun 1st person  3d game and you eventually get to find the button that turns on the ship and you get to go back to your home planet. :)
