Do you also hate spending a huge amount of money on the latest releases only to play half-developed buggy games that don’t even run properly? Well, in this article, we’re bringing you the top 11 open source games that you can not only play but also contribute to as you game along.

Alien Arena: Warriors of Mars

Alien Arena, formerly known as CodeRED: Alien Arena, is an online FPS shooter game mix between Quake and Unreal Tournament. The game is mainly about killing your enemies in deathmatches and the several team-based game modes that it offers.

There are a few objective-based game modes as well, but the game’s main focus is multiplayer. The game also has a global leaderboard for those ultra-competitive players. It’s available for Windows, Mac and Linux.

The Battle for Wesnoth

Battle for Wesnoth is a turn-based strategy game that’s surprisingly deep for a game that boasts rules as simple as this one. There’s importance on resource-management and tactical combat.

The game is based on a hexagonal map, and players can level-up their units to make them stronger. There’s also a rather deep map editor, and players can make custom content through an add-on system. There are 17 singleplayer campaigns and 55 multiplayer maps to choose from.

As the name suggests, this is an open-source Doom clone. While the source code for the original Doom game is open-source, many of the resources used were licensed. 

Freedoom aims to make Doom a truly open-source game by creating the content portion open source as well. You’d need a compatible Doom engine to be able to play the game. We recommend using Crispy Doom or ZDoom. The game is available for Windows, Linux, macOS and Android.

If you’re looking for an alternative to Microsoft’s Flight Simulator, FlightGear is your best bet. Not only is the game totally free to download and play, but it’ll also give you access to over 20,000 real-world airports included in the game’s full scenery set.

You don’t need a beast of a PC to run it either. The simulator is built with realism in mind, and the goal of the developers is to eventually build a platform for research, pilot training and other academic purposes. The game even takes weather data from METAR data that updates in real-time.
