Inspired by the classic Frontier: Elite II, Pioneer is a free and open source space adventure sim. Open-ended exploration, allowing you to do whatever you want and there's a big release out now.
The first release in some time too, with the last being in February 2019. Yesterday's update brings in an initial implementation of atmospheric lift and drag, a manual player face generator, many UI improvements, star rendering optimisation, the ship warning system also now detects missiles, a music upgrade, it's now using SDL2's AudioDevice APIs to hopefully give less crashes, more station names added and more.
A good bunch of bug fixes also made it in so you should no longer get flickering ships in the Orbit View, flight UI direction and vector indicators got fixed, a memory-leak when saving was plugged-up so it's a little more reliable and multiple other crash fishes were solved.
Nice to see another free and open source game alive and well. Any of our readers play it?
See the official site and GitHub for more info. They haven't updated the links on the official site yet, the new release can be downloaded direct from the GitHub Release Page. If you're on Arch, there's a handy package you can get here.
