Sky Boulevard: Secrets

You can find a few extra chests inside hidden room in the Sky Boulevard, but the most important secret is the Svetlana Twofeather room. There, you can find a unique augment: the Energising Augment. To find all those secrets, you will need additional gear: a Spike Sphere tech and a Rail Hook. Or you can just cheese the dungeon with any mean to fly.

Svetlana's Room

To reach Svetlana's place, you will need to find and activate 3 switches hidden through the dungeon. Once they are all activated, the bounce pads at the end of the dungeon will be activated and they will lead you to Svetlana.

First Switch

To reach Svetlana's first switch, you will need to use the Rail Hook. In the beginning of the dungeon, climb the building until you beat the Kluex Totem and use the kinetic orb cannon. Acter using the cannon, you will see a rail to your right. Use your Rail Hook to ride this rail to a small island where you will find a single house. 1 Guard is patrolling in front of the house, another one behind the house and 1 Stargazer is inside the house. The console in the house is the first switch to activate to reach Svetlana. Once you activated it, exit the house to the right, stay on top of the grey bricks and pull the wall lever. You will fall and land in a pool of water at the beginning of the dungeon.

Second Switch

The second switch is located in the Observatory, to the left of the Kluex Totem you face if you take the Stargazer Ship path. The Observatory is guarded by 2 Guards and 1 Stargazer. Head inside the room in the top right corner of the Observatory and interact with the red jewel. It will turn green and it is the second switch to reach Svetlana.

Third Switch

To reach the third switch, you will also need the Rail Hook. Head to the pyramid near the end of the dungeon by following the main path. To the left of the pyramid, you will find a cannon that you are supposed to use to continue the dungeon. Instead, exit the cannon room to the left and look down: you can see a rail leading down.

Jump into the void and use your rail hook to land to safety. You will reach a small island where you will find a house. Inside the house, activate the red jewel to turn it green and activate the cannon at the end of the dungeon leading to Svetlana. You will find a lever at the bottom of the well to the right that will make you fall safely in a pool below.

Reaching Svetlana

Once all 3 switches are activated, head to the very end of the dungeon. Above the final teleporter to exit the dungeon, the kinetic cannon is now activated. Use this cannon and you will reach Svetlana's house. To the left of her house, you will find 4 chests, the one on the right having the Energising Augment. To the left of those chests, you will find a teleporter to exit the dungeon.

Hidden Rooms

Room near Svetlana's first Switch

There's a hidden room inside the house where you find Svetlana's first switch. To open it, you will first need to go to the Stargazer Ship. In the bottom left room, you can find a small switch on the wall.

After activating this switch, head back the first building you find to the right of the Ship. There you will see a switch in the floor with an opening below you. To reach this switch, you will need to use the Spike Sphere.

Once you activated this switch, head to the house where you find the first Svetlana's switch. You will find a path open in the chimney of the house, leading you to a small room with 2 chests.

Room inside the pyramid

Near the end of the dungeon, you can enter a small pyramid where you will have to destroy a few Kluex Sentry. The pyramid hides a secret room, but you will need to pull a lever at the beginning of the dungeon to reach it. Head to the Stargazer Ship at the beginning of the dungeon. If you climb on top of its sails, you will find a lever. Pull that lever and head to the pyramid.

The pyramid is located near the end of the dungeon. Just follow the main path and you will reach it. Enter the pyramid through the gate and cross the lava pool, either using lava immunity or a Spike Sphere tech to go above the lava. You will then reach a room where 5 Kluex Sentry will attack you. Once they are all dead, the doors will open and you will find 2 chest in the room to the left. If you pulled the lever in the Stargazer Ship, use your Spike Sphere to climb the conduit above those 2 chests to reach a hidden room, where you'll find 2 Pixels dispensers and 2 tombs for more loot.

Chest below the second ship

I wouldn't recommend to go for this chest: it is a single chest and it can be tricky to reach. To the right of the pyramid, you will find another ship. You can exit the ship through the hole for its anchor to reach small islands with lava. Making your way through these islands, you will reach the final island where a single chest awaits you.
