I have thought about three units that will add variety to the covenant.
POR: The DRAGON. Basically a super vampire. It adds a 1.4 dmg. buff to the needler. and stasis abilities. It also changes the plasma cannons to a plasma charge which it will drop on units below it. The DPS for this will be the same but of the explosive type.
Cost of the upgrade is 1800
BC: The MANTIS. A super locust that adds a wraith style plasma turret and changes the Chimera Beam to a Chimera Cannon which is to be more like a particle cannon. DMG is multiplied by 1.25 and the attack style changes to armor piercing but the overcharge beam will be a beam weapon.. Like a tank however it will lose the ability to attack air with its main weapon. Dmg for the Overcharge shot will be that of the overcharge beam with the 1.25 multiplier. It would also have a 0.2 multiplier vs infantry. Finally HP would be doubled.
Cost of this upgrade is 2000
Arby gets something a little different: Elite shock troopers. These will not be a super unit they are a second unique unit like suicide grunts. They will cost 400 and be 2 pop. for a good reason as you will see. They have personal shields and health being (3000 and 3000). They also carry a fuel rod gun and shield gauntlet. DPS (400 (basic))
Upgrade 1: FLIGHT PACK: cost 400: Adds a flight pack that through an active Y ability they can turn into flying units but, they would still have heavy infantry armor. DPS x 1.1 HP x 1.2
Upgrade 2: SUPREME GAUNTLET: cost 600: Shield gauntlet is turned into a supreme gauntlet. DPS x 1.1 HP x 1.5
Upgrade 3: LAST STAND: cost 1000: If a EST hp is below 25% he gets a 50% Dmg boost DPS x 1.2 HP x 1.4
NOTES: The EST can be flamed and stuned when they fly. The reason that the vampire became the DRAGON is because vampires are a cool unit and I was trying to avoid a mainline super units because that's the UNSC's thing. Same for the MANTIS. The EST were created because this would add more diversity to the game as far as leaders go. Yes, the MANTIS is a direct counter to the GRIZZLIES but it will be beaten by ODST or HAWKS. The dragon must fly over the units to drop its bombs thus encouraging micro and the DPS for the bombs is not outrageous as it does not get upped just changed.
Any balance suggestions are welcome. Maybe number tweaks. If you have other ideas or comments please post.
My wraiths should kill HAWKS and COBRAS and HUNTERS like a GRIZZLY CAN
