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.
So why play Warcraft2 with the Stratagus engine instead of
the original Warcraft2 one ? There are numerous reasons, first it
allows you to play Warcraft2 under GNU/Linux and other operating
systems not supported by the original Warcraft2 engine, secondly
it allows you to play over the internet, which the original
Warcraft2 engine didn't allow you to. Last not least the
Stratagus engine allows you to tweak numerous parameters so you
can play around with different unit strength and such.
Since Wargus uses a different engine, not all things will work
100% the same as they did in the original Warcraft2, if you want
the original unchanged Warcraft2 experience, you will still have
to use the original Warcraft2.
Wargus is not an official Blizzard product, its a
Warcraft2 modification, by Warcraft2 fans for Warcraft2 fans.
You need a copy of the original Warcraft2 DOS version to make
use of Wargus, it will not work with the Battle.net Edition.
