Settlement 17

The East side of Blockrock is known as Settlement 17. It is just east of Robin's house on the edge of Blockrock. Settlement 17 lodges multiple characters and buildings including Elro and his family (Building 5), a ChemiCo Contra (Buiding 6,) the Community Centre, Petra and her family (Building 9) and a local Church. It works as a hub for most of the game housing a crafting table, save point and multiple statues of Mother. There are only a couple of instances when, because of the main story, certain parts of the settlement become inaccessible but are quickly resolved. Settlement 17 also serves as the start point or part of three side quests: Leticia and Fitzroy's Legend, The Love Letter, and Mother's Coroners Whereabouts. Chest Locations Chest #1 The first chest is on your way to the Glass Straight and can be accessed as you come back to Settlement 17 with the Roller Bomb Shot. In the Kerthunk fight arena you will find an illusory wall at the bottom left blocked by a wall of boulders. Shoot it with an explosive from the Roller Bomb Shot and reveal a dynamo which needs to be charged. Charge it and head immediately to the right to find the chest in the middle of the water and ready to be opened. Chest #2 A locked chest can be found in front of Petra's house (Building 9). The key can be found above her house and can be accessed a couple of ways:
 * Use the Usurper Shot by the end of the game to lower the key.
 * Using the double jump tweak, double jumping and shooting a charged shot downward should allow you to reach it.

Schematics After starting The Love Letter side quest with Laurie in Isilugar, visit Joel's house. You can find his house to the right of Petra's house (Building 9) behind an illusory wall. After trading letters between the two Joel will give you the schematic "Anxiety" for your troubles. (Labeled In Purple on the map)

Extras A note can be found near the edge of the water by the end of the game on the way to the Glass Straight. (Labled in Cyan in the Settlement 17 map) Gallery
