Flawless All Weapons Exploit
No video yet as I cant record sound atm, but il give you guys a chance to find this exploit yourselves. Should you find out the exploit could you please refrain from positing it on youtube before I do, thanks in advance.
Basically the exploit is this, become anonymous. Once you do, the game gets REALLY interesting. You can also loot guards. How to do it, il let you guys figure it out.
Become anonymous...in a fighting challenge...? Do you use smoke bomb somehow? Off the top of my head, that's what I'm thinking. Probably not it.
I'm away for the next week but will investigate after that, Smoke bombs and the side bits off the arena could be combined to become anonymous, never tried it though as I never saw how it could be useful, looking forward to the video 
Hmmm. Smoke bombs would help. And probably poison. I'm just wondering what gets "REALLY interesting" when you are anonymous. 
That was fast... yea I use smoke bombs and hide in the side bits of the arena, if you use one and gather up all the enemies in the smoke, you can pin them and keep using smokes until you become anonymous. You can then loot bodies to get the smokes back. And it is VERY helpful, its pretty much gamebreaking. I dont think il be going to my parents anytime soon, I will record it tonight but it wont have sound...
You can just use one of the many...great...songs...in Youtube's non-copyrighted...list...sigh...
Screw that. I'd rather watch a video without sound than one with one of those awful songs.
Oh! That reminds me! My new pc can handle making videos at a fast rate now! I still have my easycap, but IIRC, don't I need a code for the software to work when I put it in? If I can get past that, I'll join Jack in multiplayer madness!
I gave this a try after I posted. If you lead all the enemies to one of the side bits and throw a smoke then run and hide in the side bit on the opposite side of the place you will become anonymous before they can get to you. After that they just stand there. If you poison them instead of just plain killing not as many enemies respawn at once. However looting back the right things is based on chance.
Screw that. I'd rather watch a video without sound than one with one of those awful songs.
Or you can just turn the volume off.
Yeah you got it Aurel. I did the same as you, until I realised you dont even need to run across the map. Simply use one smoke from inside the corridor side bit as usual, but then use a second one to pin them there.
I then use throwing knives to kill 3 at once, and then I simply face 3 at a time. You can also take out the brutes and seekers with the crossbow to eliminate the challenge completely. One the very last wave unarmed agile guards keep spawning ( I used another smoke to lose them but more spawned)
These guys probably make it harder, you cant block or counter the punch, you can dodge though.
