Pioneer is a space adventure game set in the Milky Way galaxy at the turn of the 31st century. The game is open-ended, and you are free to explore the millions of starsystems in the game. You can land on planets, slingshot past gas giants, and burn yourself to a crisp flying between binary star systems. You can try you hand at piracy, make your fortune trading between systems, or do missions for the various factions fighting for power, freedom or self-determination.
Here Pioneer Scout mod creator Walterar shows us what Pluto looks like in his mod. This might have been an epic voyage for the New Horizons probe which launched way back in January 19th, 2006 but in Pioneer you can do this trip in a much shorter time. Especially so with an Eagle Long Range Fighter! :)
