what IS warhammer universe???

Eh? Just how heavy is that rock you have been living under? JUST KIDDING!

Originally it started as a table-top strategy game. Complete with minature models and everything. Check out the Games Workshop website.

Games Workshop

There are 2 main divisions inside Warhammer, The original and the 40K. The original is the fantasy based and the 40K is set 40,000 years in the future. Right now for the PC there is Dawn of War That has so far 1 expansion and supposedly another coming out for it sometime this year. I would guess that this should just about sum up what exactly Warhammer is.
