Dawn of War II Retribution. New units and skins.
Loved Greathammer. The gameplay additions are great. The added skins for various units are a big plus. My favorite addition is builder units for every race to build cover and other structures. It really adds to the ambiance. Second favorite addition is increased squad size. It brings a more epic and authentic scale but it's not over the top. My only gripes are the lack of persistent bodies, broken text on many units/abilities, and the fact that the added race, Tau, has a lot of Imperial Guard units. For now my go-to mod is ELITE with a popcap mod.
