Portal 2 Custom Level

I challenged myself to develop a level that would introduce and teach multiple separate mechanics to the player before integrating each into one single puzzle where each must be used simultaneously to solve it. I made this level for Portal 2 (2011) due to its long standing legacy of great level design and the great in-game editor. This project culminated in the creation of “Orange and Blue, Tunnels and Goo”, a custom level that aims to teach the player


For this project I used the in game Portal 2 Level Editor modified with BEEMod2 for greater level editing capabilities.

Orange and Blue, Tunnels and Goo is available on the Steam workshop and can be played for free if you have the Portal 2 base game on Steam. Each published iteration of the level can be found and played through the download button above. I also wrote blog entries as I worked on developing this level as to track my progress, which can be read here.
