Unvanquished, a free open-source first-person shooter and strategy game created by Unvanquished Development.

Players fight online in team based combat in a war of aliens against humans. The game is available for most major platforms (Linux, Mac and Windows). Support for other platforms (BSD derivatives, iPhone, etc.) is partially completed but not officially supported.


While the humans are equipped with weapons that they use to exterminate the alien presence, the aliens have only their pincers and a few special attacks, such as poison gas, and ranged electrical and projectile attacks. Players do not spawn at random points in the map; instead, each map has default spawn points and both teams are capable of moving them wherever they please. Both teams have other buildings that round out their base, such as machinegun turrets for the humans and barricades for the aliens. Either team wins by destroying the opposing team's spawn points and killing any remaining members of that team before they are able to build any more spawn points or the game timer ends.

Earlier versions of play were based on a port of Tremulous, however Unvanquished is under heavy development and is quickly becoming a very different game. We aim to provide a transparent development process that is open to the community, and frequently publish releases. We use the Daemon engine, which is a fork of the Wolfenstein: Enemy Territory engine (combining features from both ET:Xreal and OpenWolf), and provides a number of modern graphics and features over Tremulous' ioQuake3-based engine.

Alpha 6 Updates:

The new turret! Surprise! We've managed to animate it in the time allotted, and you can now construct the first new human building available in Unvanquished. As always, for best results, make sure to view it on the new renderer.
The new human HUD! It has all sorts of neat new features. Ammunition is visible both numerically and via clip icons. Stamina can be kept track of much more easily with bar we've added.
A preview of the new alien HUD! It's in a bit of a rough state, but it's working and should give you a hint of what we have in mind. Since it's still in progress, we'd like to know what you think of it, and what you'd like to see changed, added, or removed.
A new acid gas effect! The acid tube, which will be renamed once we can think up a better name for it, has a new gas effect that better reflects the maximum range of its attack.
A new grenade effect! Grenades now give off a more detailed explosion, complete with a lingering gray smoke cloud.
A growing effect! The new alien buildings, which at the moment are the acid tube and trapper, will grow in size until they reach their functioning forms at the end of the build timer.
Massive code cleanup! We've removed over 200,000 lines of code from the engine, and we've also made numerous optimizations. Memory usage should be lower, especially on servers.
URI support! If you click these links, you'll be taken directly in-game to the server in question. This should be useful for our servers subforum, and to put on your clan webpage.
Other engine changes! They can be found in this blog post.
Note: if you don't see servers in-game, make sure to delete the protocol part from your autogen.cfg in the profiles folder.
