Welcome to the Portal Multiplayer testing initiative!

Portal: Multiplayer is a modification for the first Portal, which only requires Source SDK Base 2013 Singleplayer.

This mod re-creates the gameplay of an unreleased multiplayer mode that Valve had planned for Portal,

now with new and exciting additions!

You can play the original Portal campaign together, or play an entirely new Co-Op campaign, as well as other gamemodes coming in the future!

What has happened since the last post?

If you've seen my Youtube channel, you should've noticed I'm not dead I'm still developing Portal: Multiplayer. I didn't have time to make a article about updates on Portal: Multiplayer. This is because I've been helping creating a port of Absynthe onto the ASW Branch of the Source Engine. I've been improving the port since the first video of the port. I've uploaded three videos to show gameplay of the ASW Branch.

Absynthe ASW Port (Update)


Absynthe ASW - absynthe.bsp

With all of that out of the way I would like anybody to join the development of Crowbar Studios the team would heavily need in mappers, texturer, and modelers because of as of right now we only have four people including me. So if you have what it takes to join the development message me you can contact me via email/discord/steam.
