Portal Stories: MEL
Portal Stories: MEL is a Standalone modification for portal. Great, sometimes harder than Portal’s 1&2 puzzles, custom voice acting and a good story.
+ Challenging puzzles.
+ Great story and it’s placement (I don’t want to spoiler).
+ It’s free mod but you need to have Portal 2 in your library.
+ 1 hour of great Soundtrack.
– Some bugs for example you can bypass puzzle just by jumping over blocks.
Great fun for free for every portal fan.
