I've been working on this map during the last month or so, and I think I've fixed enough obvious exploits. It's cooperative puzzle focused on light bridges and conversion gel. (You shouldn't need much conversion gel. I think five placements are enough to complete the map.) Screenshots: http://imgur.com/a/0suw8 Anyway, playthroughs would be greatly appreciated. Suggestions will be taken seriously, especially if it's something I can actually fix. I'm more concerned with making this map good than releasing it soon (or I would have already released it).

include <coop_brain> This is my second created cooperation map. And remember: Turrets are not our friends! You should take a long view to solve this map. Finally, if you find bugs, report them. ---------- version 1.2: This "new" map is now a little bit harder to solve it. ---------- version 1.3: Well, I decided to change some areas which also makes this map harder to solve. And I decided to upload the map. difficulty: 8/10 (hard) (I think it should be acceptable...) duration: expert: less than 20 minutes advanced: between 20 minutes and 45 minutes beginner: more than 45 minutes Have fun

Tired of the many basic attempts at creating an Overgrown version of the Portal 1 aesthetic? The Flawol Overgrown Portal 1 Pack (or FOP1P, pronounced 'fop-ip') has you covered! This pack aims to resolve this problem by faithfully remixing all the texture set of Portal 1 in the Portal 2 Overgrown style. This pack features: 27 textures, composing of every possible variant for the Concrete, Metal and Plastic texture sets all lovingly damaged faithful to their looks - and more! Blend Materials for every possible floor variation! With both of Portal 2's dirt and moss blends being used! Every P1 Test Chamber Model retextured and adapted with a remake of P2's Craquelure texture, creating an authentic Valve-style look to the models. (Pellet Models and Turret not included) Credit is Required

This is a test concept I wanted to try. I may make more with this testing element ; I am not sure. The testing element is a cube that freezes when you drop it, and drops when you hit it. It's relatively easy to make: it's a prop_physics with a cube world model. When it is dropped, it puts itself to Sleep, and when it is picked up, it Wakes. The skin changes to demonstrate this. To play, unzip the file and drag the .bsp into your maps folder ( steam/steamapps/common/portal 2/sdk_content/maps )

Donuts aren't good for your body, but this map is good for your brain. Actually, it's meant to mess with your head. Look around. Explore. Look behind you. Strange things happen. Unzip the file, put some sprinkles on it and stick it in your maps folder.

The BSP's have a different name, but I came up with this name after the fact. It's a journey through abandoned industrial upwards to BTS. I focused on making stunning aesthetics (or at least I think they should be). Most people know what to do with the files, but if you're not sure, place the BSP files in the games Maps folder. Steam/ steamapps/ common/ portal 2/ portal2/ maps.
