it has to do with the amount of interactions the weapons have with the world. There are a lot more actions in Gears 5 than in previous games. The animation system was completely new in Gears 4 so while we have access to the code, we have to rebuild the whole feature.
Heavy weapons are finicky. They have their own movement set, They require a lot of rigging and the mortar requires it’s own HUD and firing system.
It’s not that in and of itself it’s impossible, it’s just that if we do it, we may lose a creature or a few other weapons.
