Introducing the mod that really needs no introduction. I don't really want to give away any spoilers, so I'll try to keep it short and to the point.I would recommend having an extra 2gb of storage space available on your SHIELD's Internal Storage. The download itself is 826mb and the installation itself is even larger. Alternatively, you could download it to your External SDCard and only extract it to the portal folder, which would save you some internal storage space.- Download this file: https://www.androidfilehost.com/?fid=23622183712467400 - Follow the guide at http://r3pwn.github.io/sourcemodding.html from "What to do?" downwards. (Use the instructions for Portal modding, obviously)- Shoot me a PM or a Hangout telling me what you think of the port.As for actually playing the game, I wouldn't recommend it unless you are REALLY good with Portals. It's pretty difficult. It had me mumbling profanities to myself on Test Chamber 1. If, however, you need a walkthrough, they are available at http://www.portalprelude.com/walkthrough.php
