MustaphaTR's D2K mod is a small mod based on original D2K mod of OpenRA. It includes 8 sides (Atreides, Fremen, Ixians, Harkonnen, Corrino, Ordos, Mercenaries, Smugglers) as playable and has special units and abilities for each.
From left to right:
Atreides, Harkonnen, Ordos, Freman, Imperial, Smuggler, Mercenary
Their Powers again left to right:
Longer Range, Better Armor, Quicker to Move and Turn, Cost Less, Bigger Damage, Quciker to Build, Quicker to Fire
Cool. I like the little things like this. Even have different models.
