Pioneer is a free and open source space trading and combat simulator video game inspired by the commercial proprietary Frontier: Elite 2.

The player may choose from one of three starting locations: Mars, New Hope or a space station around Barnard's Star.

[7] The game has no set objective, and the player is free to explore the galaxy and accrue money by performing tasks like trading, piracy or combat missions, allowing them to achieve a higher rank, buy better ships and equipment and hire more crew.

[13] In 2014 Pioneer was described by PCGamer as "incredibly slick" and named among the "ten top fan remade classics you can play for free right now".

[14] In 2015 a Der Standard article noted the enormous work the fans have achieved with Pioneer as Elite remake and continuation.
