Red Alter was a total conversion based on C&C3;: Tiberium Wars, based on own alternate history of WWII ending and later Cold War, which gone hot.
New unit - Mobile Crane. Now you can make or find crane and start build a faction, no more lonely units in boxes :)
So will these work like in Mid-East Crisis 2?
I played Mid-East Crysis maybe 6 years ago, and no remember how is there :)
Due to technical limitations they had this weird thing where bulldozer could move and you could place buildings from regular CnC3 construction menu next to it, but also the construction radius in which you could build structures wouldn't update with moving bulldozer - so you'd have to cancel construction placement and select it again to see current range if bulldozer moved. It was fine but also fell very hacky and awkward, because of hardcoded limitations.
