"The Centurion has been set to detonate. Lieutenant Miller, we need you to board the ship and deactivate the A2 bomb. Should Lieutenant Miller fall, we'll have no way of stopping the detonation sequence. Judging by the state of the Centurion, you don't have much time left. Once the lieutenant reaches the ship, Squad E will concentrate on the enemy's amphibious tank. Its armor looks extremely durable, so the radiator may be its only vulnerable spot. And even the radiator is armored, so aiming with normal methods could prove difficult. But there is an opening just big enough for a soldier to reach from the top of the tank. Engineers should be able to set up ladder on the side and back of tank. Also, you can target the guns on the tank to put a damper on its firepower. Destroying all the guns ought to give you a chance at safely reaching the radiator."
Location: Schwartzgrad, Port
Description: Defeat the giant tank! Get Riley to the target in 3 turns or fewer, then destroy all 4 radiators. Ship Orders are currently available.
"You're cleared for deployment, Squad E. Please, let's end this once and for all."
Differences in The Final Battle (Hard)
2 turns instead of 3 to get Riley to the Centurion (this is also reflected on the mission description).
All enemies become level 30 Paragons.
All enemies gain improved weapons and armor.
10 turns instead of 20 to destroy all radiators.
Different placement for some enemy infantry, plus some additional ones.
Anti-tank and anti-personnel mines are placed in certain areas.
An air intake valve for the Lophius is targetable from the front. Hitting it will reduce its movement for the turn.
This mission can easily be beaten in two turns by equipping Riley Miller with an Elias anti-tank mortar, loading her and an Engineer into the Cactus, and driving towards the Centurion on the first turn. Make sure to eliminate the nearby Grenadier and Lancer so the Cactus survives. On the second turn, the Lophius will resurface nearby; issue the Blast Boost, Penetration and Attack Weak Spot Orders to Riley, and then target the middle of the Lophius, between all four radiators. Firing at this spot twice will destroy all four radiators simultaneously and end the mission.
