I would think it is due to the unpopularity among people who play it. It could also be that it wouldn't work well/be too overpowered in the 3D mode

Also the mortar, monkey engineer and dartling gun aren't returning either so there are 4 towers missing unfortunately.

But yeah, sad to see them all go ;(
