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.
Ok, that's what i ended up with.
I'll need to modify Suicide Bombers tho. As apperanelty Demolition: tag doesn't have a Type: support. So i can't use that on 2 different unit who enters different types of units. I'll make Suicide Bomberse like RA2 Terrorists for now. Until that'll be added hopefully on next version of OpenRA.
