For anyone using this in a project

The current up-to-date version of this fork is on the matchmaking branch. The main branch is several years out of date.

The branch p2-engine contains an experimental port of the project to the Portal 2 engine branch using Emulsion headers, but it doesn't yet compile/function.

Portal 2 In The Alien Swarm Engine

What is P2ASW?
P2ASW is a free project aiming to recreate most of Portal 2's entities and functions in the ASW engine SDK.
The source code is available in this repository, and is based on leaked Portal & CSGO code and reverse engineered code.

P2ASW is not finished, certain features/entities might not exist or work properly.
