Wargus is a Warcraft2 Mod that allows you to play Warcraft2 with the Stratagus engine, as
opposed to play it with the original Warcraft2 one. So unless you have a legal copy of
Warcraft2 (original DOS Version required, won't work with the battle.net edition) Wargus
will be pretty useless to you, since it doesn't come with any graphics or sounds itself.
There is no official package available for openSUSE Leap 15.5
