Friday night score! Happened across several pre-release Super Wing Commander screenshots. Note the older VDU graphics and the early cockpit that's more TIE Fighter than Hornet!
A preview build seems to have been provided to magazines in early 1994... wonder if it's floating around somewhere! Here's what the finished cockpits looked like.
And here's some footage of a pre-release build, from a VHS trailer. You can see the same WIP VDU images... plus a cut enemy ship at the 28 second mark!
