Jak 1 but you must collect Power Cells in some specific order, randomly determined when you start a new game! If you try to collect the incorrect cell, you won't be able to. Once you collect the specified cell, the next in the list is revealed. Original idea and version by SixRock and Dexz.
Some cell orderings would be impossible, like if the very first cell chosen was from Lava Tube. To avoid these cases, there are a handful of restrictions enforced when randomly choosing cells. Additionally, depending on which speedrun tricks you are comfortable with, you can toggle other restrictions on/off. (shoutout to Six & Dexz again for originally working out most of these)
Restrictions:
- Unless all 4 Geyser Rock cells have been chosen, cells outside Geyser Rock cannot be chosen (the first 4 cells are always from Geyser Rock)
- For each hub level, Oracle cell #2 cannot be chosen before Oracle cell #1
- Similarly, the Volcanic Crater miners' cells cannot be chosen out of order
- Unless Purple Rings cell has been chosen, Blue Rings cell cannot be chosen
- Unless Fish Game cell has been chosen, Misty Island cells cannot be chosen
- Unless End of Fire Canyon cell has been chosen, cells beyond Fire Canyon cannot be chosen
- Unless End of Mountain Pass cell has been chosen, cells beyond Mountain Pass cannot be chosen
- Unless End of Mountain Pass cell has been chosen, and 2 more cells have been chosen since then, Snowy Mountain cells cannot be chosen
- If any Forbidden Jungle cells have been chosen, the Mayor's 90 orbs cell cannot be chosen before his cell from Forbidden Jungle Mirrors
- If any Precursor Basin cells have been chosen, the Geologist's 90 orbs cell cannot be chosen before her cell for the Lightning Moles
- If any Precursor Basin cells have been chosen, the Gambler's 90 orbs cell cannot be chosen before his cell for Dead Man's Gorge

- No early Plant Boss - Unless Blue Eco Switch cell has been chosen, Plant Boss cell cannot be chosen
- No early Beach Tower - Unless Blue Eco Switch cell has been chosen, Sentinel Beach Cannon Tower cell cannot be chosen
- No Fire Canyon Skip - Unless 20 cells have been chosen, cells from Fire Canyon (or beyond, by earlier restriction) cannot be chosen

- No Snowy Fort w/o FlutFlut - Unless Sentinel Beach FlutFlut cell has been chosen, the Snowy Fort Gate cell cannot be chosen
- No Snowy Fort break-in - Unless Snowy Fort Gate cell has been chosen, the cell inside Snowy Fort and Snowy Scout Flies cell cannot be chosen
- No Lava Tube Skip - Unless 72 cells have been chosen, cells from Lava Tube or beyond cannot be chosen
- No Citadel Hops - Unless End of Lava Tube has been chosen, cells in Citadel cannot be chosen
- No Citadel Skip - Unless Blue, Red, and Yellow Sage cells have been chosen, Green Sage cell cannot be chosen
You can toggle these from the in-game pause menu: OPTIONS
> GAME OPTIONS
> RANDOM CELL ORDER SETTINGS
. Note that the cell order list is generated whenever you start a new game, so toggling these settings will have no effect mid-game.
