Its not a scenario, its the new space race victory screen ... by the looks of it the ships spiral in towards the the earth like planet near the center and which ever one get there first wins. The wreaked space ship over at the side makes me wonder if they can somehow attack each other? and the circling planets make me wonder if you need to avoid colisions with them?Holy cow, is that first pic really one of the scenarios, with Civ4 in space? That looks like it's from a completely different game.
I hope they include the option to do the space race without it winning/ending the game.
