Note: in Windows 7, open 'Program Files (x86)', not 'Program Files'.
Once downloaded, just extract all 3 parts to your Dawn of War - Soulstorm directory ('C:\Program Files\THQ\Dawn of War - Soulstorm', unless you are running the steam version, in which case it is 'C:\Program Files\Steam\steamapps\common\dawn of war soulstorm'). In addition, there are expansions on some of the Soulstorm races, such as Chaos Legions (9 Original Traitor Legions and Renegades) and Space Marines (Remaining 6 First Founding Legions, and 3 Second Founding Legions), Orks (Clans) and Eldar (Craftworlds).
On top of this there are seven, yes seven, new races:Ĭhaos Renegades (The Lost and the Damned)
The Codex mod aims to increase the the level of enjoyment with each existing Soulstorm race, but at the same time increase the amount of Codex units in each race, adding many new units, characters, researches and upgrades.
