0 A.D. is an free open-source real time strategy game which runs natively on Linux. It is inspired by the Age Of Empires series. Unlike most of the other Linux games, which honestly feel half-baked, 0 A.D. has a distinctive commercial-quality.

Wildfire Games, which is behind the 0 A.D. project, has just released the first alpha of 0 A.D. And they have made it super easy for Ubuntu users to install it by setting up a PPA.

But before we get to how to install it, here is a video of the game:

(In case you cannot see the embedded video here is the link – http://www.youtube.com/watch?v=x2QgByWOhR8)

So, if you want to try out this game, open the terminal and execute the following commands:

Note: It is currently available only for Ubuntu 10.04 Lucid Lynx.

sudo add-apt-repository ppa:wfg/0ad

sudo apt-get update

sudo apt-get install 0ad

Now wait for the download and the installation to finish. After that it will be found under Applications > Games. This is only an alpha release, so expect some rough edges.

If you have installed it, let us know what you think of the game in the comments.
