Seismic Activity

Guide to investigating seismic activity in Batman: Arkham Knight. Learn how to defeat militia forces, including Drone Tanks and Cobra Tanks, and return Ivy to GCPD.

Alright, so you've got a new objective marker pop up in the middle of Miagani Island, right on Grand Avenue. Head over there, and as soon as you hit that spot, things are gonna get intense. Get ready, because a Batmobile battle is about to kick off!

Your first big task is to take down a bunch of militia forces attacking the Botanical Gardens. You're looking at sixteen Drone Tanks in total: eight standard Rattlers, three Diamondbacks, a Mamba, and four of the new Twin Rattlers. These Twin Rattlers are basically souped-up Rattlers with two cannons on top, making them tougher to dodge and giving them double the armor. Keep an eye out for those targeting lasers – you'll want to use your dodge or just maneuver out of the way. Aiming for the turret area is your best bet for dealing the most damage and taking out the standard units quickly. If you can keep hitting enemies without taking damage, you'll charge up your Missile Barrage, which is super useful for clearing out groups and speeding up the fight.

Once you've dealt with that first wave, you'll get word that five Cobra Tanks have been deployed on Miagani Island. These guys are a bit more of a challenge. The best approach is to wait for them to spread out a bit. Use your mini-map to sneak up on them from behind, avoiding detection. Once you've got a lock, aim for their weak spots to take them down. Remember, after you destroy one Cobra, it's smart to evade the others for a bit before picking your next target. Keep this up until all five Cobras are gone.

After you've taken down all the Cobras, you'll get new objectives. Head back to the Botanical Gardens and make your way to the top level. Look for the indicated tree and interact with it to trigger a scene. This will wrap up the 'Seismic Activity' part of the campaign.
