Okay. The older versions got that Custom Techbuilding that kenz made for flying units. But it didnt work good (I removed it in final). I removed watchtower in final version. So you dont have to worry about that. There was also a "cave" that you can access with air units (fixed that in fixed). I builded lights with preview in older versions. The final is build on high. And the tiberium fields didnt (almost) had no tiberium meshes. I got way more tiberium now (btw. Final got blue tiberium)
Final version has also no pickups. There was a problem with it. You could pick every weapon that was spawned around the map. These days we have that the player can hold 2 weapons, 1 pistol, a grenade or bomb (Was also in Black Dawn)
