When we took an overview of the remarkable happenings in the potato sack ARG yesterday, the trail was going cold, and it looked as though things were winding down. For a few hours at least, they were, then it all kicked off again. New updates have added Portal 2 themed levels to many of the games in the potato sack sale. The voice of Glados has started appearing in menu screens and secret messages, and to top it all, Bit.Trip Beat creators, Gaijin, dropped a heavy hint that completing the ARG could cause Portal 2 to be released early.
Adding fuel to that theory, today Portal 2 became available to pre-load through Steam. We've collected videos and screenshots of the new Portal 2 themed levels from potato sack sale below.
The Ball
The Ball gets a good extra hour of free Portal 2 levels, including one devoted to bowling over Aperture Science turrets. The team have done a great job of recreating Portal 2's assets in the Unreal 3 engine.
Audiosurf
The Portal 2 update in Audiosurf replaces your ship with a portal gun, and adds companion cube blocks to the courses. The best update is the addition of new Portal 2 songs like the one in the video above. After a couple of listens, it really gets stuck in the brain.
Bit.Trip Beat
Glados has well and truly invaded Bit.Trip Beat with this difficult new level. Gaijin hinted in their latest blog post that more ARG clues will be revealed to those who achieve perfect completions of the new levels.
AaAaAA!!! - A Reckless Disregard for Gravity
Glados has a lot to say about falling off tall objects after the latest Portal 2 update to A Reckless Disregard for Gravity. Creators Dejobaan also created a brilliant overview of the progress of the ARG so far, ending with Glados' invasion of the potato sack games.
RUSH
What better way to combine Portal 2 with Rush than to add companion cubes? It's almost as cute as the Portal 2 level in Toki Tori below.
Toki Tori
Toki Tori's levels provided plenty of useful clues during the ARG. Their silhouettes formed decipherable codes that helped to unlock the passwords for the Aperture Science login screens. The new level has Glados hanging in the background, watching your every move.
Killing Floor
The new Killing Floor map has you fending off waves of zombies in a massive new Aperture Science map. The familiar human vendors have been replaced by a robot that looks just like one of Glados' personality spheres. It looks great, too, with its overgrown test chambers and giant buttons. You'll find their official screens of the new map below.
