Here are my suggestions for more Air and Water units:
--- Air lab ---
WindBag - as a equivalent to Dirtboxes WindBags can be used to catch up to 2 shots of a chainsaw - 20 metal.
T-Fighter - they are like Avengers, but without Air-only weapon - 75 metal.
Construction Airplane modification: instead of construct with a costant rate parts with up to 100 metal can be build within recharge zones like at the airplane lab or on reload pads.
The this Airplay flies to the build location and drops a nano particle construction bomb at this building - reclaiming at the same way.
--- Gunship lab ---
Nanomissle drones - instead of much AOE damages this suicide drones only a single target, but does more damage.
Construction Unit modification - it needs some time to deploy itself at the ground an can build anything in a little bit larger radius - 250 metal and 6m/s
--- Ship lab ---
Intel Test: a mobile radar / jammer unit with switchable cloacking.
Remove Subs from this lab.
--- Sub lab ---
Add a sub con like the current air constructor.
Add from ship lab removed units.
Add swarm subs like Puppy
Add a shield sub
--- Buildings for air and water ---
Add a sub nano turret for 250 metal.
Make the shipyard a under water building like a gunship lab build on seabed.
Add a Sub lab
Make newton buildable on seabed - letal to ship only attacks.
Make shields and sneaky pete buildable in water - we can build it with terraform anyway.
--- really new buildings and units ---
Add laser pallisades: they fire at each other all the time if they have LOS and avoid the infiltration of the own base better than LLTs.
Add seismic dedectors - It should only be able to dedect the nearest 10 units.
add vision missles to the missle silo - they make anything visible in a wide line toward the destination.
Add teleporter - move the unit next to them, then with shift click next to another one and then to the destination.
> the teleporter can dedect near destinations and redirect it over itself if the next destination is next to another teleporter.
Add a defensive building who needs a base building not busy to fire.
> Defensive point = wormhole for output of weapon fire
> Base building is like a Annihilator but less efficient / more expensive because some energy is needed to get the laser through the wormhole to the Defensive point.
> Suggestion 2.5k metal for the base building, 500 metal for the defensive building.
> Increase fire frequency with more base buildings and distribute it over all defensive parts who need it.
