Armoured enemies would be great, some more turrets, and some upgrade paths for the turrets. Thanks.
Edit:
Helicopter, Plane, Boat enemies. With armoured and camo variants.
Rail gun, anti-air, I need more turrets i just do really know.
Also by upgrade paths i mean each gun has like 1 path with a base version and a level 3.
Than a base with a few upgrade levels. Or just a taller flag to show its a higher level.
If this is alot to ask for sorry. I am willing to pay more as I really like this style :)
