For the past 3 years I've been working on "Linux Air Combat". The design and coding are now stable, with version 5.64. This is a free, open-source, 3d combat flight simulator for LINUX, themed on World War II, and simulating more than 50 different types of WW2 aircraft. Networked, multiplayer missions support both tactical and strategic combat involving destruction of enemy airfields. Here's a screenshot:

YouTube has a lot of video clips about LAC. Here's a short review of a version from about 3 months ago:

I hope you enjoy this. It's published with full, very CLEAN source code that easily compiles, with no need for modifications or tweaking, on all  major LINUX desktop distributions. The itch.io download also includes a precompiled binary that is compatible with recent 64-bit versions of Ubuntu LINUX and PcLinuxOs.

Glad to see linux first games!

Hi Leafo. I decided to make LAC "Linux Only" because Windows users already have access to many fine flight simulators, dating back to the "classic" period around and even before the turn of the century, and I wanted to give LINUX users the same kind of experience. I also didn't want to "compete" with any of the Windows-based flight sims because that community has also been very good to me, but some of those communities are struggling right now, and I don't want to take away their devoted users.

Update: As of this date (25Jul2019), LINUX Air Combat version 7.65 is the latest, greatest version. It is interoperable with all prior versions since 7.56, which was released in April 2019. Users with older versions should upgrade in order to participate online with the LAC community through our free server at LinuxAirCombat.com.

Recent improvements focus on more accurate flight models and more interesting online combat missions. Our online community is small, but we get together every Thursday evening for amazing online battles. Here's a YouTube video clip showing a recent example:

Update Jan2024: LAC has continued to evolve, and now it's no longer necessary to compile from source code because we distribute it in the well-known, precompiled, prelinked "AppImage" format for compatibility with all of the popular desktop LINUX distros using industry standard "X86" hardware!
