Hey, welcome to the Forums.

I don't know anything about the Demo version, but I think you might want to get on better terms with the badguys they have some cool ships.

One tip, buy the real thing.

you can't fly the other ships in the demo because you don't have a high enough level to buy some of them. The ships "available" are Starflier, startracker, patriot, rhino, defender, and I think there's a dagger for sale at either Buffalo or Rochester. --- RR16

Whoever came up with "Mission Commision" should be lined up and shot

Look Here for Demo MODs:
Demo Mod: 5 ships Levels reduced
Demo Mod: Cheap Mod
Demo Mod: Weapon and Ship Mod v.0.3
Hope this help

Thanks BlazeME I have been trying to fly the defender for awhile and thanks to you I can.

Thanks Whimseyboy
