I thought I was going to hate this, and during I was a bit stumped because I thought I screwed myself over by starting with the sniper rifle in the ICA safe house. I thought to myself as to how am I going to move this sniper in my suit and if I have a guard move it for me, it's going into the mansion and I can't enter to recover it.
So I tried a couple of things, took a few VERY dangerous chances and ending up finding him because I just so happened to remember where he could be based on my extensive playtime on my favorite map. And I just so happened to find him by accident because I was a little frustrated that I was stuck about my position while with the rifle.
Also, I want to mention that you said in the rules that we can't enter Caruso *mansion. But we are allowed on the grounds, correct? If so, I passed. If not, I failed. I didn't enter his mansion, but I was on his mansion's grounds.
I'm uploading the video now. Ill tell you where to start from and you can tell me if I passed or not so you don't have to sift through the entire run.
