Hint: Find a way to use portals in the future that will allow you to use portals placed in a different location in the present.Luckily, your portals fired in the present will not move in the future, unless you relocate them in the future. Hint: The Material Emancipation Grill has a different position in the future than in the present.Or perhaps, jumping on a Weighted Storage Cube. Hint: There are various ways of increasing your position in the vertical spacial dimension.Hint: If the future Weighted Storage Cube is taken to the present timeline, moving the present Weighted Storage Cube will cease the future Cube’s existence in the present timeline.

Find a way to obtain another Weighted Storage Cube. Hint: Two Weighted Storage Cubes are necessary to complete this puzzle.Hint: Many chambers in this game cannot be solved in the present.If you are genuinely getting stuck at this point, then I hope your puzzle-solving skills will dramatically increase as you continue through this game, because this does not bode well considering the difficulties of the next twenty-three puzzles. If you are struggling with this, there are many other “helpful” guides that will tell you how to move and look around. Use your mouse and keyboard/controller to find and press it.

Nevertheless, waiting twenty years is not the recommended solution.

Hint: Despite what the voice in your head says, you will not die of thirst if you keep waiting.

Hint: You should read this hint after you have read the first hint.

Hint: Since this is a mod of Portal 2, you should have fully completed Portal 2 before playing this game, which is quite simple because you must own Portal 2 to play this game.

Hints are given in increasing order of clarity, so you should look at the first hint in the list first.
