Portal: Revolution
Wenn die Laufzeit die Wertung entscheidet
First Impressions
Steam calls it Overwhelmingly Positive. Across all languages and purchase types, 28,994 of 30,136 reviews are positive — 96% as of 2026-09-21. For a free unofficial expansion to Portal 2, that looks like a closed case.
Read the 1,142 negative reviews in helpfulness order, though, and the complaint converges on one thing. Not the puzzles. Not the difficulty. The walking.
Sorting the top twenty negative reviews by theme: backtracking and travel distance leads with seven. Then the voice and chatter of the core character Stirling at six, the Portal 2 plot rehash at five, and inconsistent difficulty at five.
So the verdict here is not settled inside the chambers. It is settled between them. That is an unusual seam for a free fan project to split along.

Putting the Mechanics into Words
The positive side names a short list of new things: a cube that redirects lasers, a water hazard, and an early stretch where you can only fire one portal. Those three come up again and again.
The single-portal stretch is what Puzzlebyrinth calls subtracting a verb. Where Portal 2 expanded by adding gels and funnels, this one opens by taking something away. Same hardware, opposite thinking at the entrance.
Critics writing for the press say the same restriction is used to good effect. That reads to me like subtraction doing its proper job as a doorway into the learning curve.
But subtraction is only finished when the verb comes back. How a game celebrates that release matters, and the positive reviews go quiet exactly there. I noticed the silence.

The Texture of Difficulty
Difficulty is already split inside the positive pool. People writing recommendations say it is easy for anyone who finished Portal 2, then, a few lines later, that a couple of chambers genuinely made them think.
The negative side is blunter: difficulty that never settles, solutions that fall out of trial and error, a thin payoff at the end. The phrase that keeps returning is that the aha is missing.
What interests me is the store page, where the developers say testing was thorough enough that every player can solve the puzzles. That claim and the review pool fit together better than they look.
A chamber flattened so that everyone clears it has a shallower trough. A shallow trough means a lower view from the top. Solving and feeling that you solved are different targets, and this project chose the first. Portals are a legible mechanic to begin with.

Pacing
Movement is the most written-about thing in this game. Too much walking. Sent back again. The same steps a second time. The largest bloc of the negative pool sits here.
In design terms this is a ratio: time spent finding the solution against time spent executing it. Stretch the second and the feeling of having solved something drains away on the walk back.
Portal 2's test chambers are mostly closed, and they end roughly when the answer arrives. This one walks you through the facility between chambers. Portal Reloaded extended the room inward, along time; this extends it outward, along distance.
Eight hours is a number a fan project can be proud of. Some of it is bought with footsteps. Pad a runtime with steps rather than chambers and the complaint always lands right here.

Place in the Lineage
Two reference points recur in the reviews: Portal 2 itself and Portal Stories: Mel. That tracks — development is reported to have begun in 2016, when Stefan Heinz set out to build something in Mel's wake.
The technical base is said to be Strata Source, a Source engine variant descended from the Portal 2 community edition work. Release was January 6, 2024, on Windows and Linux, free.
Two rulers end up in play: astonishing for a mod, and a rehash as Portal. The 96% is a score on the first ruler. The reviews calling the plot a Portal 2 retread are reaching for the second.
The press praised the puzzles as consistently strong and named Stirling the weak link. Users agree about the character, not about the puzzles. Critics grade eight hours as a whole; players grade the one chamber where they stalled.

Closing
I land on 8.2. The gap from Steam's 96% comes from two places: a runtime padded with travel, and a plot borrowed whole.
Neither objection misses what the project was for. It was not built to be a new Portal. It was built so you could walk that facility once more, and forty chambers spread over eight hours serve that aim.
It suits players who finished Portal 2 long enough ago to want those white walls again. It does not suit anyone who wants chambers and solutions by the shortest path; for them the footsteps are pure waiting.
Free does not excuse the flaws, but it does widen the reach. That an outside team can handle the vocabulary built up since Portal in 2007 explains at least part of those 30,136 reviews.
