Intervention

**Intervention** is the second subchapter of Chapter 2: Old Site in Celeste. The subchapter is primarily focused on a chase sequence in which Badeline follows the player by mimicking their inputs. This subchapter also features the first appearance of key tokens and their key-activated platforms, a recurring set of objects for the game. Additionally, Madeline interacts with Badeline for the first time at the start of the subchapter. The subchapter ends with Madeline using a payphone to answer a call from an unknown character before being confronted once more by Badeline, after which Madeline is consumed by a monster imitating the look of the payphone, causing her to wake up.

## **Gameplay**

After the cutscene at the beginning of the subchapter, every input by the player will be copied by Badeline as she chases behind. Coming into contact with Badeline will result in instant death. Many of the screens feature key tokens, which the player must collect to open the door to the next area. In order to avoid coming into contact with Badeline, however, the player must move across the room without recrossing their path. Since it is very easy to slip up and die by dashing into a space block the wrong way, it is recommended to plan out your moves before you make them, pausing if you need.

The fifth room can be very daunting if you don't know the best way to approach it, so try first dashing straight up the space block for the top key token, then move left and dash left during your descent to get the bottom left token. Approach the right side of the space block and dash diagonally upward to the left and then dash again for the third key token, and quickly get out and dash diagonally upward after touching the final one at the bottom right.

Eventually, Badeline will create two clones, causing the player to be chased by three Badelines in succession. It does not make them faster, but it does make the player more likely to be hit when retracing their previous path. Many find this section challenging, being intimidated by the extra clones. You should sometimes try to hold still for a second and then continue your movement to cause all 3 Badelines to also stop in place, allowing you to easily pass them.

For the last room within the site, the number of clones is increased by two, resulting in five total Badelines chasing the player. The room is also much longer, making it the most difficult section of the subchapter. In this room, there is a small shortcut found by the second small bridge in the room: by dashing left, a tiny tunnel can be entered, skipping a short area of the room. Lower down is another shortcut where you can pass through a small hole of the floor as long as you don't activate one of the falling platforms. This is a lot harder and riskier, though, so you should generally avoid it and go normally.

### **Strawberries**

There are 8 Strawberries found in this subchapter.

Berry 1

Found in the second room of the subchapter, this Strawberry forces you to detour from the exit by going up-right from the space block. For the most consistent collect, dash right into the berry, climb up and wait a bit, then jump back left.

Berry 2

Found in the third room of the subchapter, you can see this Strawberry inside a wall but with no real way to get it. In order to reach this area, you have to dash straight left from the right side of the space block just above the spikes. To make sure Badeline doesn't hit you, grab the berry and cling to the right wall, then dash to the left wall when she approaches and escape like normal.

Berry 3

Found in the sixth room of the subchapter, the berry is located in the top-left corner. Dash up one side of the wall, jump to the other side and grab the Strawberry, and slide down the wall.

Berry 4

From the seventh room in the subchapter, you can notice an opening in the ceiling between 2 walls filled with spikes. Try to get yourself under the second space block in the room, then dash straight up and move left a bit before dashing straight up again. From there you can get into the room above and collect this Strawberry.

Berry 5

Found in the seventh room of the subchapter, this Strawberry is very tricky to get because you can't interact with the falling platform above it or else it will block off the berry or crush you. Try your best to grab onto the walls elevated above spikes and climb them to jump into the pit with the berry, then quickly dash out and finish the room.

Berry 6

Found in the eighth room of the subchapter, you can approach this berry differently depending on if you take the shortcut mentioned earlier. If you do take this shortcut, simply move right from your fall and into the hole where this Strawberry is floating to collect it. If you don't, it's still possible to get this Strawberry. When you approach the large, square-shaped space block, dash through it diagonally up-right and then dash straight up to reach the berry.

Berry 7

From the eleventh room in the subchapter, you can access a screen transition at the top in the same column as the fourth space block from the left. In the room above you have to dash straight up to find the Strawberry and move left and right, dashing through the space block as you descend, to avoid your death.

Berry 8

From the eleventh room in the subchapter, another screen transition can be found in the same column as the fourth space block from the right. It's at the bottom, so to enter it you just have to dash straight down from the top of the space block. In the room below, you can make it to the Strawberry by dashing diagonally up-right from below both space blocks. Once you get to the berry, do the same but mirrored to return.
