Warhammer 40,000 Dawn of War - Winter Assault Expansion Pack
Arrived on the day of release and been playing ever since. The guard have real character and it's great to see sentinels and great armies levelling out the battlefield.
With all the new maps, enhancements and solid campaign this is a worthy upgrade of the best computer version of 40K ever.
I could write more, but I'm too busy playing it.
