**Act 4** is the fourth act of *The Entropy Centre*.

## Summary

After an elevator falls, Aria must find her way up to the floor with puzzle area 04 and is introduced to springboards.

## Walkthrough

### The elevator fall

* The elevator will fall.
* Rewind long enough to find an accessible floor.
* Take the cube from the back shelf in the puzzle room and place it in the elevator.
* Go back into the elevator and rewind it to the next floor.
* Robots will look at Aria through a window and then exit the room.
* Rewind the elevator to the next accessible floor up.
* Take the cube out and place it on the pressure plate ahead outside of the elevator.
* Go through the door.
* Rewind the stairs and the fallen platform to the right.
* There's a jump cube against the wall at the end of the room.
* Place the jump cube at the bottom of the shelves where a room is open at the top.
* Head up the stairs and onto the platform.
* Drop down onto the jump cube to get into the high room.
* There's a power device on the shelf to the right. It may be difficult to see because the back of the device is facing out.
* Pick up the power device and drop down out of the high room.
* Take the device up the stairs and across the platform to the open panel next to the door.
* Put it in the panel and rewind it back to a working state.
* Go through the door and continue through to puzzle 0401.

### Puzzle 0401

* Take the stairs down to the pedestal and interact with it to enable the springboard.
* Go back up the stairs and step on the springboard to make it across.
* Go through the door.
* Take the cube to the right and place it on the pressure plate.
* Pick it back up, turn around, and use the springboard ahead.
* Place the cube on the pressure plate here and go through the door that opens.
* Rewind the cube so it goes back to the first pressure plate.
* Go through the door that opens.
* Turn right and go through the room.
* Follow the corridor's twists and turns to reach puzzle 0402.

### Puzzle 0402

* Pick up the normal cube and place it on the nearby plate to open the far door.
* Pick up that cube again and bring it to the other plate.
* Avoid the springboard and pick up the jump cube.
* Holding the jump cube, now step on the springboard to get to the far side.
* Put the jump cube down next to the side of the upper level.
* Step on it to jump up to the upper level.
* Rewind the normal cube back to the previous plate to open the door.
* Go through the door and continue ahead to puzzle 0403.

### Puzzle 0403

* Go down the stairs and into the office.
* The computer on the desk has two emails providing intel.
* Exit the office and go to the far side of the room.
* Pick up the jump cube. (Don't repair the broken platform just yet.)
* Bring the jump cube to the side of the next highest level. Keep the rewind data intact.
* Step on the jump cube to jump to the next highest level.
* Step on the springboard to jump across.
* Rewind the jump cube back to the orange square.
* Stop the rewind. (Jump cubes don't function when their time is frozen.)
* With the necessary rewind stop completed, rewind the platform in the distance to rebuild it.
* Step on the springboard to jump forward, landing on the jump cube, and then being flung up to the platform.
* Go forward through the doors into the HR area.
* Check the farthest computer behind the HR desk for two emails providing intel.
* Go up the stairs to reach puzzle 0404.

### Puzzle 0404

* Go to the right and pick up the cube.
* Hold the cube over the springboard and delete rewind data.
* Then place the cube on the plate that opens the door.
* Go through the door and rewind the cube, but don't drop it onto the springboard just yet.
* Stand on the plate that shuts off the time gate.
* Stop rewind so that the cube drops and is flung through the inactive time gate.
* Move the cube to the plate that opens the door on this side.
* Continue through the door forward and around left to reach puzzle 0405.

### Puzzle 0405

* Pick up the jump cube and take it to the corner by the upper level with the exit to the puzzle.
* Place it on the floor against the left side of the gap.
* Delete the jump cube's rewind data.
* Pick the jump cube back up, turn around, and set it on the first plate to the left to open the door above.
* Pick it up again and set it on the plate to the left.
* When the platform at the back moves fully to the other side, go up the stairs and step on the springboard.
* After landing on the platform, rewind the jump cube so that it's on the plate that opens the door.
* Go through the door.
* Rewind the cube back to the gap.
* Stop the rewind so that the jump cube works.
* Jump onto the jump cube to be boosted to the other side of the gap.
* Proceed ahead into the elevator.
