I did it much simpler.
Just isolated targets in the Cinema with weapon trick and did the job
Finally did the last two, the part 1/2 ones. Part one had a target that was a lure fest, coin coin coin, which is my least favorite aspect of Hitman honestly. Part two was much better with some cool kills, though I will admit I couldn’t be arsed to isolate the main woman and just knifed her from cover, getting 4 stars. I make sure to 5 star contracts/escalations I really enjoy, but otherwise… meh.
I enjoyed the first two sets of promotional featured contracts a good bit, but they’ve been less good as they’ve gone. Or my standards have gone up. I dunno.
I’m not familiar with the (other) trick to get ‘Eyesbreaker’… It’s either something with the tranq gun or the sniper exploit with the gauchos NOT shooting the watermelon. 
I just did the disguise/weapon chase.
-
KO the guard in the bathroom and get his disguise. Hide all bodies.
-
Use the weapon lure/chase exploit while disguised as the guard.
-
Run ahead of the target, switch back to your suit and get into the 1st bathroom and equip the sniper rifle.
-
The targets will go to where you left the disguise (or go the guards body?)
as you snipe them from behind.
I’ve used this ‘trick’ in another contract that I’ve made, even in the Censor ET. But this is the first time I’ve had a target go to the body instead of the disguise. 
@CHAOS_AGENT_45 As I mentioned in CJs chat today.
Cool, more featured contracts that you can’t SA without some kind of glitch. I’m glad I didn’t waste my time trying to figure the sniper one out.
Got a couple of #1’s and a pair of #2’s. I can only stumble thru Eyesbreaker, so props to you guys doing it so well! Mendoza is my favorite map with Chongqing being a close second. Explosions and poisonings are my specialty. Dig those the most!
@Parsime and me proved it’s doable without any glitch. But i have to say it a bad sniper contract for such a sniper frindly map…
