The anchor challenged the "Portway" wall exchange MOD is like a new game

Portal is not only one of the most creative puzzle games in history, but also its design is exquisite.Valve's talented designers have created every puzzle that challenges Euclid's geometry with surgical precision, gradually guiding players to master the ability to "think with portals".

The core of all this lies in the placement rules of the portal in the game: the portal can only be opened on the white concrete wall of the test pod, and the black metal surface will invalidate the portal in the spark.

These limitations are the key to the Portal puzzle charm.But what would happen if these wall attributes were completely exchanged? Foreign anchor Marblr recently came up with this bold idea. He reversed the texture of all walls in the game through MOD - concrete turns into metal, and metal turns into concrete."When the whole game was remade with inverted textures, an obvious question arose: Can you still pass this level?" Marblr thought.

On this basis, Marblr also adds some extra rules and exceptions.Although most of the interactive surfaces in the test compartment are interchangeable, there are a few exceptions: for example, the metal surface under the black mucus pool remains unchanged, after all, falling into mucus will cause Cher to die instantly, and swapping them has no practical significance.

In addition, the concrete wall with fixed portal frames has not been changed, as changing these will directly destroy the logic of the related puzzles.Finally, considering that this inversion is likely to break the original puzzle-solving logic of Portal, Marblr declares: "Any vulnerability or exploitation mechanism operation is allowed as long as it is within the scope of each map."

As Marblr discovered, the results were surprising."Some levels become extremely simple and even easier than the original ones because of texture reversals; while others are bad and almost impossible to resolve," he explained.

This is vividly displayed in the beginning of the reversal of the texture.The MOD version was pretty normal at first, until Marblr got the first teleportation gun - this gun could only fire one portal.In the original game, the next few levels were all concrete walls, and after being reversed, they all turned into metal walls, which means Marblr had nowhere to put portals at all.

Therefore, Marblr has to use speed-pass techniques such as "accelerate jump" (to increase speed through repeated jumps to cross gaps) and "prop climb" (to repeatedly jump on holdable objects such as radio or blocks to climb up the wall).But when a metal wall appears in the sixth level (which becomes a concrete wall after being reversed), Marblr suddenly can skip the entire puzzle directly - since the wall at the end of the level is now concrete, he can directly teleport to the elevator.

Game video:

The wonder of texture reversal is that it essentially turns Portal into a brand new puzzle game.Admittedly, this "new game" has much worse balance and requires players to have an in-depth understanding of the skills and bugs of "Portway".But if you have played "Portway" countless times, this way of playing will have a unique appeal.

Marblr's video is well worth watching in full.If you want to try the reverse version of "Portway" yourself, the MOD he produced has been launched on the ModDB platform.Of course, if you want to solve the reversal puzzle yourself, don't watch the video first - but given that some solutions are extremely difficult, you may eventually refer to his strategy.
