Iron Man & All Armors vs Sentinels (The Matrix)
Iron Man (in his last suit), War-Machine and Iron Heart are in Zion. 250.000 Sentinels are about to invade Zion. All 90+ (93?) armors are present and controlled by J.A.R.V.I.S. Besides Iron Man's armors, Tony has managed to get a hold of the Iron Monger armor and Vanko's/Hammers drones. They are also controlled by JARVIS.
Can they hold out and defeat all Sentinels, entering Zion as quick as the drilled holes allows them, or are they overrun? They get about 2 hours to prep for the incoming attack.
