Explore the Aquarium
The main entrance of the Aquarium will be locked, so we need to head around to the right side. Crawl through the fence and climb into the building.

When inside, you will eventually climb up a ladder and jump down into a darker area. In this room, you can pick up 9 Parts & 6 Supplements.
Moments after this, you need to crawl through an air duct in order to continue. Dropping down at the end, we are forced to fight against a dog. At this spot, there are 17 Parts on a shelf to our left.

Our only collectible in this chapter is a Journal Entry. To obtain it, open the bag in the kitchen area.
Going through the door with the crab painted on will advance the story and result in a series of cutscenes.
This finishes Chapter 22: Infiltration in The Last of Us Part 2. Next is Chapter 23: Tracking Lesson.

Hi, I’m stuck on this part because when the dog jumps at me I’m automatically killed without the chance to fight with the square button. I tried reloading the checkpoint and even the chapter from the main menu but still doesn’t work. I think it’s a bug. Any idea what I can do? Thanks.

You could try to change the controller mapping in the menu and manually assign other buttons for certain actions.
Check the accessibility section for other combat-related options and/or change the difficulty for a bit.

Maybe try to heal ur self before the fall… Did u go there with low health ?
Vk says
Having the same problem. Did you figure this out ?
Adam says
In the accessibility menu, switch the button from “tap” to “hold”. Had to do this myself and it worked on the first try.
Windian says
There is a Locked Door in the room we inspect the Collectible… Is there anyway to get inside that Door ?
S1LB0T says
Not as Ellie.
ed says
Has anyone solved the Infiltration problem about the dog when Ellie falls down?The melee button does not work and the dog keeps killing me.
dan says
Hi vic and vk, did you find a solution to the problem. I can’t progress from the dog at Infiltration. The melee is not working no matter what I do. Glitch?
