Chapter 7: Nature Always Wins

Investigate the Seismic Activity on Miagani Island

After receiving the Batmobile upgrade, Alfred informs Batman of seismic activity on Miagani Island and that contact with Lucius Fox has been lost. The former pertains to the main story path while the latter begins the Friend in Need Most Wanted. Drive to the waypoint near Miagani Botanical Gardens to investigate the seismicactivity.

Work with Poison Ivy to defeat the Militia Forces Attacking the Botanical Gardens

The Arkham Knight sends in 24 drones to deal with Poison Ivy including Rattler Drones, Diamondbacks, and Twin Rattlers. Help her defend the Botanical Gardens from the onslaught of militia vehicles. The drones surround the area, making for some tough situations with shots coming from all directions. Stay on the move, using the Vulcan Gun and Heavy Cannon to wipe out the forces.

Next, five Cobra Drones are sent to the area. Remember, to take this drone out, sneak up behind it and, once the target has been acquired, fire the Heavy Cannon at the weak point to destroy it instantly. Maneuver around the buildings to get behind a drone. As the Batmobile nears an intersection, check the radar to verify that it is safe to continue. The tanks occasionally perform a 360-degree scan, where they stop and spin their sensor all the way around to detect anything nearby. Quickly duck behind cover if you're caught in their field of view.

Pick Up Poison Ivy and Return Her to GCPD

With the area clear of drones, return to Miagani Botanical Gardens and eject from the Batmobile. Land on the top level of the structure and interact with the plant to pick up Poison Ivy, but she insists on remaining at the gardens. Meanwhile, Alfred interrupts with information on the Cloudburst. The Arkham Knight mans the Cloudburst Tank as it drives across Perdition Bridge to Bleake Island. An explosion rocks the city, causing chaos throughout and making the Batmobile inoperable.

Interrogate Simon Stagg to Find a Way to Defeat the Cloudburst Tank

Glide and grapple back to Stagg’s airships on Founders’ Island, sticking to the rooftops to avoid the toxin. Enter Airship Beta through the hole on the front, targeting one of the hostiles ahead. Seven unarmed-soldiers, including a medic and a brute, must be taken down before proceeding inside. Step up to the door as Batman equips the Voice Synthesizer. Stagg’s voice must be used to gain access to the zeppelin and fortunately, a sampling has already been recorded. Use the device to calibrate the sample and then use it on the panel to open the door.

Proceed through the biometric gate ahead to reach Biological Engineering, where eight militia soldiers also search for Simon Stagg. Two Boa Sentry Drone operators and two medics highlight this predator zone. The room should be familiar as it was used in a similar fight earlier in the story. The Arkham Knight’s voice has already been synthesized, so use the Voice Synthesizer to order the combatants around. A good way to start the fight is to command a medic to investigate the area around Stagg’s cage, allowing Batman to scoop him up from the vantage point. Work your way around the area and silently take the rest down, paying particular attention to the remaining medic.

Track Down Simon Stagg Using His Fingerprint Trail

Approach Stagg’s cage on the near side of the room and activate Detective Mode to pick up his fingerprints. Follow the trail down the steps to the lower level and through the corridor with the primate cages. This leads to a handprint on a floor panel. Open it to find Stagg, cowering inside. Batman interrogates the scientist to find out about the Nimbus Power Cell that is required to drive through the toxin.

Use the Nimbus Power Cell to Repair the Batmobile

Exit the airship and return to the Batmobile on Miagani Island. Land at the waypoint on the nearby rooftop. Press the Call Batmobile button to start the repair. Slowly remove the power core from the vehicle. When attacked, press Counter to counter the thug. With the Nimbus Power Cell inserted, slowly push it back in.

Use the Batmobile Sonar to Locate and Release Ivy’s Plant on Founders’ Island

Behind the wheel of the Batmobile, accelerate away from Botanical Gardens and drive to Founders’ Island, where Ivy knows of a buried tree that might help. Be on the lookout for tanks still roaming the island. Fire the sonar to reveal the tree’s root system on the radar. Head east and then south and hit the sonar again to display the tree, represented by the dot on the radar. Drive onto that spot and hold the button to fire a Charged Seismic Sonar Blast, but it is not strong enough to release the tree. Batman must find a way to get closer.

Gain Access to the Subway Network Via the Elevator at Port Adams to Get Deep Enough Underground to Release Ivy’s Plant

Follow the waypoint to a gate on the south side of the island. Once opened, drive inside where the Arkham Knight has placed a number of drones in defense, including a Python, Diamondbacks, and Rattlers. Stay on the move along the tracks and take them all down with the Heavy Cannon and Vulcan Gun, remembering to use the special abilities when available. On the southwest end of the port, a ramp offers entry into the container yard. Hit the Afterburner and jump inside.

This rapid assault aircraft flies around the battlefield firing its machine gun and rockets at the Batmobile. It is easily shot out of the air with the Vulcan Gun or part of a Missile Barrage, but combine this pest with a group of drones and it can eat away at a vehicle’s armor. Look out for circles on the ground, as this is where it targets its projectiles.

Much like the Mamba Drone, this static missile platform fires guided missiles that must be shot out of the air with the Vulcan Gun. That is where the similarities end though. This well-armored drone does not move and it fires a low-and-straight-flying rocket along with the missiles. Listen for the warning beeps and dodge to the side while taking out the projectiles.

More Rattler Drones must be dealt with before finding the elevator. Strafe around the containers for protection and pick off the remaining tanks. Once the area is secure, find the freight lift in the northeast quadrant of the yard and pull off the door with the Power Winch. Fire the winch at the motor inside, drive inside, and rev the engine to power it up.

Use the Batmobile Sonar to Locate and Release Ivy’s Plant on Founders’ Island

Follow the subway tracks and drive up the right side to avoid the first gate. Keep the speed up and continue to the top, hitting the Afterburner to clear the second. Hop out at the closed gate ahead and drop into the floor grate. On the other side of the obstruction, a Rattler stands guard. Blind it temporarily with the Remote Hacking Device before exiting the floor. Note that only one drone can be disabled at a time. Run past the tank, duck behind the right wall, and wait for a patrolling Rattler to turn around. Note the blue light that represents the Rattlers’ field of vision.

Step around the corner to find a third Rattler tucked in a cubbyhole. Quickly, disable the gun as it scans to your left. Continue forward and hit the Rattler Drone ahead with the hacking device. Run past the tank and grapple up to the beam above. Four more Rattlers occupy the corner ahead. Swing to the next girder, glide behind the tanks, and enter the control room. Throw the switch to unlock the security gate that blocks the Batmobile.

Bring your vehicle to Batman’s location, destroying the militia’s Rattler Drones along the way. Around the corner, the Batmobile is blocked again. Toggle to Batman and throw the switch that sits next to the gate. Enter the vehicle and continue to load zone A, where a raised platform prevents going any further. Eject from the car, enter the control room ahead, and unlock the ramp. Use the remote to drive the Batmobile up the new path as the vigilante hops inside.

Round the corner and pick up speed as the Batmobile approaches a gate ahead. Drive up the side and squeeze through the opening on top. Continue around to the bottom to slip underneath a fan. Stay on the gas and drive along the left side to avoid a pool of water. Slow up after the dip in the road and drive up the path on the right to reach another ramp and a gap full of water. Exit the vehicle, grapple over to the control room ahead, and find the switch inside. Unlock the ramp to lean it toward Batman and then drive the Batmobile onto it. Drive to the other side, switch back to Batman, and lock the ramp. Now it can be used to clear the water. Punch the Afterburner to reach the other side.

Drive up the steps to the right and mow over the bollards. Use the Sonar to find the plant. Drive through the weak wall to the left to find the spot. Fire a charged Seismic Sonar Blast to loosen the ground. This releases the plant as it deposits the Batmobile above ground in Divinity Churchyard on Founders’ Island.

Protect Ivy’s Plant from the Militia Forces While It Matures

Before you know it, 40 drones descend on the area. A wide variety of vehicles take part, including Diamondbacks, Rattlers, Twin Rattlers, Dragons, Mambas, and a Python Drone. Poison Ivy gets assistance from her plants, so don’t worry if something emerges from the ground. Stay alert for incoming projectiles. Dodge the rockets and shoot down the guided missiles. It is important to use your special abilities when available, but it also helps to have a Missile Barrage ready when surrounded.

Destroy the Arkham Knight’s Cloudburst Tank

With the Batmobile’s telemetry functional again, it is now time to go after Arkham Knight and his tank. Drive to Bleake Island where Batman instructs Alfred to raise the bridges. This confines the tank battle to the one island. Six Cobra Drones guard the Cloudburst Tank. Avoid the boss while concentrating on the Cobras. The big tank’s location is noted on the radar with a vehicle-looking icon as opposed to the generic pointer of the Cobra Drones. Taking care of the drones first allows time for Alfred to find a weakness.

Arkham Knight’s assault vehicle is a well-armored tank with a powerful energy weapon. It is constantly scanning 360-degrees around his vehicle. Steer clear of this guy as much as possible as the Batmobile takes considerable damage if you directly take on the Cloudburst Tank.

Touch the drone and the player takes damage. When spotted, the boss attempts to lock on to his target. A horizontal bar, in the middle of the HUD, expands outward. Once full, a strong energy shot is fired. As long as you remain targeted, he continues to discharge his gun. He eventually fires guided missiles like the Mamba and Python Drones. Listen for the warning and use the Vulcan Gun to shoot them out of the air.

With the guards out of the way, get in close to the Cloudburst Tank, keeping a wall in between you so he doesn’t notice the Batmobile. Scan to analyze the coolant lines. These four spots are the weak points, located on each side near the ground. The Batmobile is no match for this tank when taken straight on. Once its sensor passes your location, peek out from cover, lock on and fire the Heavy Cannon at the coolant lines, and fall back. This sends its core temperature to critical. A horizontal meter appears in the top middle part of the HUD and steadily lowers. Once depleted, the drone has cooled down. Simply run away from the boss during this aggressive period. Repeat this process on the coolant lines on the other three sides.

At this point a health bar appears in the upper-right corner as the Cloudburst becomes vulnerable. This is the entire bottom of the drone. The tank now begins to launch guided missiles and rockets at the Batmobile. Concentrate fire on the lower body of the tank while backing away from the irate boss. Dodge away from the circular targets on the ground to avoid the rockets and knock the missiles out of the air with the Vulcan Gun. Do not let up on the attacks until the enemy blows up. When given the opportunity, pummel the guy before he slips away.

Investigate What has Happened to Poison Ivy

Return to Poison Ivy at Miagani Botanical Gardens and interact with the tree to check on her.

Speak to GCPD Communications Officer to Investigate Possible Lead

Drive to GCPD, enter the Communications Room behind Aaron Cash, and speak with Sergeant McAllister to learn more about a broadcast over a SWAT channel. This gives Batman a way to track down Scarecrow.
