In my opinion, The Teleporter Chambers is a set of 20 of the best designed levels in the entire game. Although the teleporters have always been available in the base game, these 20 levels are designed with the teleporters in mind and it really shows. With The Teleporter Chambers, it always feels as though the sky is the limit and any route you put your mind to can probably be done. It feels fast, slick and has the right amount of challenge.
Having said that, even if you enjoyed the base game, you might not necessarily enjoy The Telerporter Chambers simply because the control scheme demands a certain level of precision to complete and eventually S-rank the levels. If the thought of doing jumping teleporter throws while flying through mid-air seems challenging, it's because it is. But that makes it all the more satisfying when you finally nail it. =)
