Rayman Redemption - Final Challenge - Dark Legacy - Hitless + Ultimate Completionist Achivement 100%

Now this.... This was insane. Recorded on 5th March. This was by far the hardest challenge in Rayman Redemption, there is no equal. True Boss Rush may have been difficult, but it only took me a day. This took me 3 days by comparison.
I was completely relieved when I had achieved this, and was absolutely astonished that I cleared, disbelieving at the time.
The first segment was decent, often reset to it randomly, but didn't pay it much mind.
The second segment is long, super precise with strange floaty infinite jump physics with the copter hair - it's as precise as it needs to be, despite being a bit weird. Either way, it's a very scary and long segment, can be very tense. This is where almost all of my runs died to until near the end, where I strangely failed to third segment a couple times and on fourth and final segment failed a couple times there, too.
The third segment has some tight spots, but for the most part was okay, it was just easy to fail, particularly the ending with the eyeballs and the lightning shots.
The fourth segment is a brutal ending, given you are timed by the water rising and you have to do many segments perfectly in a row. Sure there is breathing time towards the end of the segment, but everything is pretty precise except for the final part where you avoid the big boulder, and the part where you get carried by a platform up there, those two parts were free.
All in all, I enjoyed completing Rayman Redemption, despite the ludicrous difficulty curve of doing this challenge hitless, and the difficulty of True Boss Rush (which was okay once you put enough practice in).
Right, and getting ultimate completion unlocked HD Rayman skin. I am unsure whether the skin is unlockable by other means, or if you unlock it by getting the Trap Master or Ultimate Completion achievements. Since I did Trap Master at the end and instantly gained Ultimate Completion afterwards, I have no real way of knowing. Plus at that point I already had a 100% save file due to having completed True Boss Rush, and didn't have the HD Rayman skin until I finished this challenge hitless.
