I can't remember a map name!

I used to have a map that me and my friend used to play, and it contained a space ship.

It was where you can go into a reactor room, and throw a grenade into the reactor, run like hell, get in an escape pod and escape.

Me and him want to play it.

Only problem is, we dont know the map name.

Help?:

It was meant to be a Zombie escape map, It’s called Space Shuttle, I think. Or relevant to that.
