Thanks to the Perpetual Testing Initiative DLC's intuitive and enthralling editor, Portal 2 has a near-endless supply of new puzzles for players to enjoy. Since its release, over 200,000 new community made levels have been uploaded to the Steam Workshop, ready for a one-click download and integration into Cave Johnson's pan-dimensional scam. Whether you love lasers, revere repulsion gel or crave companion cubes (don't we all?) there's sure to be something out there.
Here's our pick of the best ten community-created puzzles available, and a further five fulsome campaigns. Obviously, with so many to choose from, some are bound to have fallen through the cracks. Be sure to share your favourites in the comments, and keep your eyes peeled for our top co-op maps in the very near future.
There's an island in the middle of the map's suspiciously brown water. On it, three buttons deactivate the emancipation grids to the three rooms off to the size. Simple enough - head to each room, collect its cube, and pop them on the switches. Except each solution requires elements from the others, leading to a puzzle that quickly has you running through what can be done where. Satisfyingly convoluted. Download Permutations here .
I'm a sucker for both gels and excursion funnels, so Goobound was already off to a promising start. It's a series of paint-based puzzles, that have you really thinking about the application of that blue bouncy goo. What really sells the map is the button-based end section, that has you figure out the sequence of ramps to raise in order to bounce yourself to the exit. Download Goobound here .
3. Four Block
Four Block is a great realisation of a segmented room theme. Unlike Permutations, here each challenge is linked only by the need to collect a cube to bring back to the small central room that acts as the main hub. It's a clever example of how to create a series of fun puzzles out of all of the game's many elements, and still have it gel together in a cohesive whole. Download Four Block here .
4. Collective Scrutiny
In Collective Scrutiny, mapper Edeslash creates a large, multi-roomed chamber, in which many of the puzzle elements are kept separate from their home by those portal and object destroying emancipation grids. Bypassing them involves directing lasers, rescuing spheres and liberal application of orange gel. It's not particularly difficult, but working through the various processes is a lot of fun.

Mevious is probably the most prolific and well known of Portal 2 mappers, thanks in no small part to a Valve made collection of his work from the Testing Initiative's beta. His levels trend towards the compact but devious, a style exemplified in Gate. You're placed on the wrong end of an emancipation grid but, despite appearances, the solution is sheer elegance in its simplicity. Download Gate here .
