I'm a strategy games fan. If i'm here, it's to find new units or gameplay to play a better and better game everyday. I'm following Command & Conquer Red Alert 3 mods, mainly Paradox. I love aircraft, and jazz.
The building pad would be a tech structure who can be captured by an engeneer. After that, the pad give a building zone where the player and his allies can build structures and defenses.
To pack up and unpack units, the special ability of the pad is to drill up and deploy somewhere on water or on ground.
Almost slower than the Talon MCV, the structure is extremely strong, can no be sell, sniped, recaptured if not destroyed. If destroyed, the structure will rest in place and delete the thing on it in a large explosion.
Another way to get one could be to capture a "Building Pad Command Center", who can command the building pad (Free, but one per command center) who land like the mercenaries in Starcraft II.
