As a Standalone "game", it's possible download and play this mod without Portal 2. — The preceding assigned comment was added by Tark {Finish Him! ▪ Contribs} 20:02, 29 July 2015 (UTC)
- It still requires that you own Portal 2 because it redistributes Portal 2's binaries. It's a content mod; not a source code mod. No Source engine game technically requires that you install the game it's based of off if you structure it correctly, even more so when they all went SteamPipe. i-ghost 21:02, 29 July 2015 (UTC)
