Are you talking about Ultimate Apocalypse, tombik?
No, actually I am talking about a collection of mods.
Ultimate Apocalypse is also nice, but not for me, since they try to modify the game, every original race as well, as well as the scale of the game. But DOW1 engine can only support so much, so it results in unintelligible chaos mostly (not that chaos).I also dont like how they change the default camera to allow a higher field of vision. I like my vanilla races as they are. And also, UA does not include every race I am about to mention.
Here is what I am aware of, all good quality mods, all better than official Dark Eldar for example:
Steel Legion
Adeptus Mechanicus
Tyranids
Chaos Daemons
Salamanders
Dark Angels
Harlequins
Black Templars
Thousand Sons
World Eaters

There is also an ongoing project in revora forums that aims to combine all these races, (there is a common developer for all of the above and he personally oversees this) and increase the race count up to 60 at the end. All the voice overs are ready, most build trees are ready, they are just in need of 3d artists and animators.
