ThinkingWithPortals’ 2011 Portal 2 Mapping Contest

The premier custom Portal and Portal 2 map community,, is proud to present the 2011 Summer Mapping Initiative! This is a Portal 2 mapping contest! is looking for clever and fun test chambers consistent with the themes in Portal 2 (which means no custom assets!).

The top two winning maps will receive the grand prize of the Ultimate Portal 2 Gift Pack, as well as having their maps spotlighted on the official Portal 2 website.


This is a mapping contest for Portal 2 – the ultimate first-person puzzle-platform video game. The main task is to create a custom level map for Portal 2.

Remember – making a puzzle extremely difficult does not necessarily make it better! Players of all skill levels will be playing and judging the maps, and while we all enjoy a good challenge, maps should be accessible to all players. But don’t take that to mean they should be “easy”!

Maps will be judged based on several factors, including:

  • Puzzle complexity
  • Visual appeal and attention to detail
  • Innovation and imaginative design
  • Adherence to an overall theme (1940’s Aperture, destroyed Aperture, etc.)
  • Overall fun and playability


The first and second place ranking maps will receive the following prizes:

  • Ultimate Portal 2 Gift Pack signed by the Portal 2 developers
  • Map spotlighted by Valve on the official Portal 2 Website
  • Community Spotlight


  • You may submit group work to the contest.
  • Both Singleplayer and Co-op maps are allowed. You may submit one map of each game mode.
  • Maps cannot contain custom assets of any kind. No exceptions. Spend your time working on your puzzle, not making models, textures, sounds/voices, or other extra content.
  • Maps must contain both an Entry and an Exit elevator, the style of which as appropriate for your map theme. 1940’s Aperture maps can use the old style elevators, destroyed Aperture can use the destroyed looking elevators, and so on.
