Hi there,
I just wanted to throw this out there. Here are some ideas for units that would make naval battles awesome.
UEF - T2 Mini Carrier.
A T2 naval vessel. It repairs, builds and launches aircraft. Has capacity to store 20 aircraft. It is able to build T1 and T2 aircraft. Including: Scouts, Interceptors, Torpeedo Bombers and Fighter Bombers. It has AA missiles and flak cannons for self defence.
Cybran - T2 Minelayer Submarine.
A T2 submarine. It has sonar stealth and can build anti-shipping mines. It has minor repair and reclaim capability. It is slow moving and has minor torpeedo capability.
Cybran - Anti-Shipping Mine.
This is a stealthed suicide structure. It is immobile and constructed by the T2 minelayer submarine. It detonates with a moderate AOE blast radius. It can be detected by underwater vision or omni-sensors. It can attack surface or submerged units. It will not attack hovercraft or seabed units. It can be targeted by depth, charges and torpeedos. It can also be reclaimed. It explodes on death, and can be manually detonated.
Aeon - T3 Mothership.
This is a T3 amphibious support vessel. It is equipped with an impressive radar system and is able to build Aeon hovering land units on water. Including the Scout, Aurora, Blaze, Assylum, Ascendant (T2 flak) and Absolver. As well as also constructing T1, T2 and T3 engineers.
Seraphim - T3 Hovering Transport.
This is a hover unit, built at a T3 naval factory. It functions in the same manner as an air transport, except that it is a hover unit. As such it is not targeted by AA, but is able to move on land and sea. It has a higer movement speed than most land units. But is slower then air transports. It has more HP, a personal shield and beam weapons. It can be used to ferry units to land, or to quickly deploy hovercraft on water.
