There was a game like this, you guided a scientist out of a lab or something. I forgot the name, but I remember it from way back when I was 13 (2 years back). 

I know this is an old post, but was trying to find the same game and finding very little info. Hopefully, this will help someone else. The game you're thinking of was Mayday:Deep Space. For whatever reason, it is not longer in the app store so I couldn't find it in my past purchases.
