Portal 2 stands out as one of the most mod-friendly video games ever, offering an in-built level editor and seamless access to its underlying Source engine. This accessibility has led to a vibrant community where enthusiastic fans have created numerous fangames and mods, many of which are easily discoverable on platforms like Steam’s Community-Made Mods page.
Harnessing the creativity of its dedicated fanbase, there are many mods available to enhance the game with new narratives and mechanics. In this article, I will dive into these mods, exclusively from the Community-Made page, to provide a comprehensive ranking based on their overall quality and originality. If you notice any omissions, they may be due to being ineligible, such as mods for the first Portal game or unreleased ones.
7 Portal: Forbidden Testing Tracks
Uses Generative AI, -10 Rep

At the bottom of the ranking is Forbidden Testing Tracks, a mod marred by numerous technical flaws. Players often encounter crashes upon adjusting audio settings and are unable to toggle subtitles, leading to an overall frustrating experience. Amplifying these issues, the game’s choice to employ AI-generated narration instead of engaging actual voice talent is disappointing.
While the incorporation of portals reminiscent of Minecraft’s Immersive Portals mod is an intriguing concept, it falls short in execution, with most puzzles proving less compelling than similar creations in Minecraft. The mod’s lack of polish, alongside its annoying sound design and ineffective mechanics, make it a disheartening inclusion in the Portal mod community.
6 Aperture Tag: The Paint Gun Testing Initiative
Let’s Get Messy

Dubbed as the only paid mod in this lineup, Aperture Tag carries a $5 price tag that raises expectations it doesn’t quite meet. With visuals that appear outdated and unrefined, sound quality that leaves much to be desired, and subpar writing, this mod struggles to justify its cost. While the core mechanic—a gel-shooting paint gun—offers some physics-based puzzles, the game often relies on mechanics that feel unresponsive and hinder gameplay flow.
While a few puzzles are enjoyable, many require navigating cumbersome physics, detracting from overall enjoyment.
5 The Cleaning Game
Something Else

Ranking The Cleaning Game was challenging, as it deviates significantly from the Portal series. Instead of intricate puzzles, it presents a narrative-driven experience focused on cleaning up an office, resulting in a meditative exploration of choice and consequence.
This mod evokes an interesting twist on Portal 2 by fostering an ambiance akin to a Powerwash Simulator but with a darker undertone. For players seeking traditional Portal puzzles, this may not satisfy, but it’s worth considering for those intrigued by unique narratives.
4 Thinking with Time Machine
Take it Back Now Y’all

Thinking with Time Machine embodies the spirit of indie creativity, boasting a novel concept and engaging puzzles. Although it does exhibit some janky mechanics and lacks adequate tutorials for its main gameplay element, the act of recording and replaying actions adds a unique layer of complexity to puzzles.
While other mods have interpreted time travel mechanics more intuitively, the execution here remains enjoyable, earning a strong commendation even in its brief playtime.
3 Portal Stories: Mel
A Step Back

Portal Stories: Mel introduces players to an unused character from the original game, Mel, navigating through the neglected parts of Aperture. This mod boasts stunning environments and a gripping atmosphere that feels authentic, despite not being produced by Valve.
Beautifully crafted visual elements and engaging voice work enhance the experience, yet the gameplay suffers from frequently unclear puzzles and inconsistent physics, which can frustrate players aiming for the precision typical of the Portal series.
2 Portal Reloaded
Time to Party

If players can endure a lengthy introduction and a somewhat bland narrator, Portal Reloaded offers rewarding puzzles that evoke the essence of the original. The introduction of a third portal invites multidimensional thinking and enriches the gameplay experience.
Unlike many fan projects, this mod carefully curates its difficulty curve, akin to the polished experiences produced by Valve, featuring innovative future mechanics and even some entertaining multiplayer levels. However, it suffers visually from a lack of distinctiveness and occasional performance hitches during autosaves.
1 Portal: Revolution
Retrofit Revisit
Finally, Portal: Revolution captivates me with its rich exploratory design, although it isn’t without its flaws. For those averse to excessive dialogue, the persistent chatter might weigh down the experience, yet it showcases astonishingly intricate chamber designs.
What stands out is the effective use of mechanics that were lesser utilized in the original game, resulting in diverse gameplay that maintains the essence of the franchise. Despite the repetition of certain sequences becoming tiresome, the mod is a testament to the ongoing passion within the Portal community.
