Attack on Titan 2

Dire elimination will unlock after completing the story mode once.

After, you need to replay each story mode missions. To help you, when the mission starts press button then button to get the information on how to activate the dire elimination mission.

To track the dire elimination progress just look at the score on each missions. SS score tells you that you already complete the dire elimination.

You unlock dire eliminations after completing the game once. The way to see what you have to do in the different stages for the dire to appear, simply press start at the begging of each match and look for the Special Missions. You have to get those done without failing and the dire will appear. SS scores means you already done it. Playing on Haven Mode makes it easier.

Unlike the first game there's only 2 missions with shitty requirements this time.

First one is Eastern Line - you have to save Hannes ( which is part of the main-mission anyways) and build 7 bases. Once you saved Hannes 3 red flags will pop up. The catch is that you have to build 7 bases before interacting with the final of these 3 flags which would spawn the final group of Abnormals. Instead you have to go around the map and build or rebuild stuff until the Dire sub spawns in the corner of the map. As long as you clear the map of titans there's no time pressure since the main-base will be fine on its own.
If the final group spawned without the requirement being completed it's still gonna say "In Progress" instead of "Failure" and no matter how long you wait - the Dire sub won't spawn.

The other one is the mission that has you pushing Berthold on top of the wall. You have 3 minutes to reach him while he's doing his steam-thing. 3 Minutes are very tight and I've reached him with half of a second left.
No tips for this one, hide when the steam is rolling and try to avoid the rubble flying down while pushing. I got hit once or twice and still made it.
