You mean this one? (at 1:48)

I'm just guessing but I saw you on www list of this server few days ago so maybe you have found it by yourself there. I wanted even enter for few minutes to show you stuff but I had no time at the moment. If you've discovered it while being alone on server, without help - congrats man. Usually I had to show how to start most of my mods which work on some maps. At least this is how it was for last 2 years.
Icarus Wings mod was mad to make CJ Flying possible in 6156 version of Crysis. In 5767 it works (glitch) without any mods same as Wall Jumping (just 10x harder to learn). I wanted to show you some of those classic Crysis glitches last week (as I was saying in e-mail), but I guess our time zones will always be a problem :)
Since we were talking about Wall Jumping already - but not about Circle Jumping yet (I wasn't bringing it up because it's only for 5767 - unless you use Icarus Wings mod on some of 6156 servers/maps) - I'm reminding some of 4 years old tutorials about that CJ/WJ in 5767 version:
http://crysisflyer.com/.
Great old times of classic Crysis MP. No mods and extras there and still lot of fun and skills to develope.
Because we were exchanging some info before - I'm almost sure you didn't know much about WJ and CJ in Classic Crysis while playing PS for years. Best things to have fun with, best things to train and develope here beside aiming.
The thing is - after last 18 months of this network I' almost sure, that ALL and I mean ALL glitches and tricks should be in Crysis MP FAQ - because players should know all glitches that exist in Crysis before even starting to play it (not have skills developed at once but at least know which glitches exist) - to avoid situations when they can't tell the difference between original glitches, server/map side mods or hacking (which almost never happens nowadays).
It's a bit confusing but after finding out what is and what's not possible in this great MP, problem can be easily solved. Finally I need to paste it somewhere on website and finally on Jumping/Flying School server - they way nobody would miss it, without searching for things or asking questions. 4 years old WJ/CJ text tutorial displayed on screen below while gaming on Jump/Fly School server is hard to notice for most of random guests.
Anyway. Congrats for your exploration and discovery - and I hope to meet finally on some server and try those things during some weekend. See you.
