Welcome to Portal Mapping and Modding, a large and welcoming community for creating and sharing fan-made content for Valve's critically acclaimed series Portal, and a hub for countless fan-games, workshop creations, and modding competitions!

This server offers a large variety of events and an extremely active community to help you with anything from learning the basics of Hammer World Editor to getting feedback on your latest creation!

We host competitive mapping jam style events several times a year with different topics, such as creating a puzzle with certain restrictions, or decorating a level with a certain aesthetic theme in mind.
