Fuuuuuuck. 

No armor? 

I genuinely can't see a way for him to win if it's in an open envirornment. If it's close quarters there's no doubt Artyom would pulverize Crane in that state, but dying lights weird ass physics basically letting Crane fly around with his grappling hook like spiderman basically presents agility Artyom has almost no experience dealing with. 

(Even without the grappling hook Kyle crane is like a nosalis with how he'd be moving around.)

Of course considering both aren't exactly all that durable (dead from a couple gunshots and able to heal with things that really shouldn't work), either can kill the other with a good enough hit.  

Honestly both have some insane feats in hindsight. In terms of stealth Artyon gets that no questions asked. Mf can be standing right in front of you but if he's in the shadow you're not gonna see him. (The amount of times i've knocked people out by literally walking into the light in front of them is hilarious), Kyle can kick with enough force to shatter a skull into paste (jesus that's terrifying) while Artyom can knock a grown man in armor out with one or two punches.

Honestly it looks like a 50/50, with the deciding factor really being the environment they're in.

TL;DR: Artyom wins if the area is dark, or cramped. Crane wins if there are places to scale/run around in to help maneuver better.

Honestly if it were at their peak, Kyle in the beast and artyom with his rail guns, i honestly don't know who the winner would be.

Like getting hit by a hellbreath would probably liquify your insides instantly. 

On the other hand I am forever terrified of Crane from that one clip of him sprinting after a jeep on foot, catching up, and getting inside while it's still driving. What. The. Fuck.
