Harbour Battle is Marine Spartan Combat....that armour is heavy, so the water will kill you!

Four Different ships have gathered in the Harbour to duke it out for control:

The "Red Ship" is a Catamaran style Light Destroyer:

She's Equipped with a deck mounted Scorpion class Artillery Cannon, a Banshee and a Falcon and a Standard array of weapons (see listing below).....

The "Blue Ship" is a Medium Cruiser:

Also Equipped with a Scorpion deck gun and a Falcon, she has a hidden Banshee launch deck in her bow.

The "Green Ship" is a Heavy Battle Carrier:

The Most Heavily Armoured of the Group, she has an undermount Scorpion Cannon, a Top Deck Wraith Mortar Gun, a Falcon and a pair of Banshees......as well as a sizable interior....

The "Orange Ship" is a landing craft:

While She lacks deck guns, she does have a pair of Stern Mounted Shade Turrets in addition to a bevy of landing craft that can attack the other ships from the island:

Not that the ships don't fire on each other....

^ Blue Firing on Orange

^ Did I mention there is a weapons drop on top of the Pillar?

Each ship has a standard array of weapons:
Gravity Hammer
Fuel Rod Cannon
Splaser
Sniper Rifle
Focus Rifle
Plasma Launcher
Rocket Launcher

The "Orange Ship" has the following landing craft:
1 Scorpion
1 Warthog (Rocket)
1 Warthog (Gauss)
2 Mongeese

Enjoy.....and please leave feedback so I can improve the idea!
