Every Phantom Thief Needs a Good Escape Route
Let’s get right into the action, shall we?
We start our pulse pounding adventure right after taking out the first enemy by using the basics of CQC.
Go down the stairs and notice the two enemies on the right side of the screen. One of the walks in a counter clockwise square around the open area on the right, and the other walks up and down the lower hallway.
You want to wait for the exact moment that the bottom enemy turns its back to look down, while the right enemy is in the process of moving a bit upwards before turning left. You need to hold Shift to sprint behind the right enemy to slip past it before it turns around, without being seen by the lower enemy.
Your first “checkpoint” is going to be this ladder right here. You’re going to need to be patient and wait here for a bit while watching the patterns the enemies go in. You should take note of three specific enemies from here on out:
-The first enemy that moves up and down the hallway, the one you just avoided and is parallel to you.
-The second enemy that moves around the bottom right corner bookshelves. It walks in a pattern of going left, down, up, right, while hugging the bookshelf directly under you.
-A third enemy which is a bit hard to keep track of, because it walks in a very large square perimeter of the entire lower area. By the time you reach the checkpoint, it should be making its round from left to right.
Your opportunity comes when the third enemy passes the hallway and moves down, which will happen at the same time the second enemy turns around. You can sneak past both of them without being seen, but you need to pause and hold still before going into the line of sight of the first enemy.
When the first enemy turns around, you are free to pass into the center of the hall. This is where it gets tricky.
You’re going to want to stop a little left of the center of the room and hold there for a moment. From this spot, neither enemy 1 nor 2 will see you. You have to be careful, however, because if you stay here too long then enemy 3 will eventually make a full circle and come up behind you.
You’ll have to move very quickly through these next few steps. When enemy 2 turns around, you want to hug the very corner of the large table. When you stand here, you shouldn’t be noticed by enemy 1 at all. Hidden in plain sight, eh?
The moment of truth… the very moment enemy 1 turns around, you need to run as fast as you can down the hallway before enemy 2 can turn around and spot you. It’s only in this brief window of time that you can slip past both of them, and you have to do it quickly before enemy 3 returns.
Run like no tomorrow. You’re in the clear, kid!
Now that’s what I call escaping with style. Congratulations! Making it this far will earn you the Phantom Thief Marisa achievement!
As an added bonus, here’s an enlarged version of the achievement icon.
And here’s a very poorly made edit I did in like two minutes, because I think without the gold border it looks better as a Discord icon.
