Ready for one more run through the testing chambers? The free and very popular mod Portal Reloaded just recently had The Cooperative Update release.
The game already expanded on the Portal idea a fair bit giving you a triple portal gun, with the third portal being a time portal so it all got a bit wibbly wobbly…time-y wimey. With this latest update it goes a little further adding in the new co-op mode with 20 new testing chambers, co-op time travel mechanics, a new narrative, new music and a whole bunch of improvements to single-player too. They've also added Finnish, Italian and Ukrainian subtitle options now too.
Check out the trailer:
Available to play on Steam, free for owners of Portal 2.
