I've beaten around 38 extremes as of uploading this rating. And of all the hard ass levels I've gone through the trouble of completing, there is only one level that has not only always captivated me, but was a god damn treat to complete as well. Cognition is by far the best level I've had the honors to beat, and by far my current favorite extreme behind Anathema (which I haven't beaten yet). There is just so much to love about this level. It's satisfying, it's classy, and it makes you feel like a pro while playing it. The song is one of the best songs used in an extreme demon and I stand by that; I LOVE electro swing Esque music. The deco works so well with the old timey yet modern mashup that is Cognition and I love it to bits for it. Oblivion could never.
