0 A.D. (pronounced “zero-ey-dee”) is a free, open-source, historical
Real Time Strategy (RTS) game currently under development by Wildfire Games,
a global group of volunteer game developers.
As the leader of an ancient civilization, you must gather the resources
you need to raise a military force and dominate your enemies.
“0 A.D.” is a time period that never actually existed: In the usual calendar,
one goes from 1 B.C. to 1 A.D. and skips zero. This reflects the historical
fiction in the game: Who would have won if all the factions were pitted
against each other when each of them was at its prime?
We intend to portray some of the major civilizations over the millennium of
500 B.C. to 500 A.D. (Hence the midpoint, zero.) That is an ambitious prospect,
so in the first edition of 0 A.D. we focus on the last five centuries B.C.
Perhaps in future expansion packs, more civilizations will be added,
along with additional gameplay features.
We put a strong emphasis on historical accuracy while developing 0 A.D.
We plan all our units and all our buildings based on reconstructions of how
the units and the buildings might have looked like in the ancient world.
We even name them in the original languages, such as Greek and Latin.
But it’s worth remembering that any game should be fun to play, so,
in many cases, we preferred playability over historical accuracy.
Swap out openSUSE_Leap_15.2 for openSUSE_Leap_15.1, openSUSE_Leap_15.0, or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
