GL-117 flight simulator
Original Release: 12 March 2005
Latest Version: 1.3 (24 April 2013)
License: GNU GPLv2
Developer: GL-117 Team
This is an OpenGL- and SDL-based action flight simulator written in C++. It provides a random terrain generator, lighting effects, sounds, and joystick support. It is an action flight simulator for Linux/Unix and MSWindows. Enter the Eagle Squadron and succeed in several challenging missions leading though different landscapes. Five predefined levels of video quality and a number of viewing ranges let you perfectly adjust the game to the performance of your system. Joystick, mouse, sound effects, music.
This game has been developed in the years 2002-2004 and is intended to run on NVidia TNT2 or GeForce2+. The latest CVS snapshot on SourceForge has been refactored to clean C++ code for a 2.0 version. However, due to changes in graphics programming, two years after the 1.3.2 release, a complete rewrite of the graphics engine would have been necessary. As the main developer is no more a student, this project has been abandoned since then. Sorry, but I hope you can still enjoy and play. Many, many thanks to all contributors!

A new fork of gl-117, known as “Linux Air Combat”, takes this classic old game to new levels. The focus is changed from arcade gaming to World War II combat flight simulation, with 54 distinct WW2 aircraft and sophisticaed, Internet-based, multiplayer missions. A google search for “Linux Air Combat” will yield LOTS of related detail. The source code is free and it compiles easily on all of the popular desktop versions of LINUX.
