It's Released!
Beta Testing
Release date: Dec 10, 2014
Rexaura is a mod for Portal. It is a story campaign with 20 chambers teaching and testing your ability to use some interesting new mechanics involving High Energy Pellets.

"It’s utterly delightful, probably the best chunk of non-Valve Portal modding I’ve played. It’s consistent with the tone, nicely paced and rewarding to play." - Rock Paper Shotgun

9.6/10 - Desura

4.88/5 - Thinking with Portals

You can download it right now for free on ModDB, Desura[], or Thinking With Portals[].

  • A 20 chamber singleplayer campaign
  • A new story and dialogue localized for English, Chinese, Spanish, and Italian
  • Several new puzzle mechanics including Flux Fields, Hydrodynamic Cube Stability Units, and Positron Energy Orbs used to manipulate and detect High Energy Pellets
  • Easter eggs which unlock bonus chambers
  • Original soundtrack featuring seven new songs


Q: How much will it cost on Steam?
A: It will be free, as it is today.

Q: If I can already play it, why add it to Steam?
A: A few reasons:
  • Easier support for Mac and Linux
  • Easy download and install
  • Easy update - Never worry if you have the latest version.
  • Steam cloud support - Saved games, collectibles, and bonus level progress won't be lost.

Q: Does this require Portal?
A: Yes, you must own Portal to play it.

Q: Why is this for Portal and not Portal 2?
A: It was originally designed back in 2011 before Portal 2 was released. If this project sees success, I would love to port this to Portal 2, remake it, or maybe make a completely new sequel.

Q: Is it any good?
A: You can read the ModDB reviews, and read about it on Rock Paper Shotgun.

Q: What's the release date?
A: It can be released as soon as it's greenlit. If you can't wait, you can get it right now (links above).

Q: Are you allowed to add a Portal mod to Steam Greenlight?
A: Yes. Here's more info.

Q: Why not just put this on the workshop?
A: Portal doesn't have workshop support and there are no public plans to add it. Even if it did, the workshop would likely not support the following features:
  • Subtitles for new voice lines
  • Localization and translations for new text
  • Unlockable bonus maps and challenges
  • Custom music with adjustable volume
  • Custom menus

Mevious, I will give you an idea: why don't you put your other mod, portal pro on Steam?
