MW3 Survival Solo Seatown wave 174 (Game freeze - weird). Part 1

First of all Its been awhile since I put last video. Theres plenty reasons why. Short answer is I played it but didnt have that much time as before and got bad luck to not get anything good in those few attempts when I could play (weird disconnections and like 1 or 2 stupid deaths). Finally I had time and I figured out Jugg and Helli strategy to get easily my first solo 200+. In my first attempt with that Jugg and Helli strategy I got robbed by game or something what is called game freeze. In this case I would rather say got robbed by game because I put 12 clays for Helli waves and game freeze. Theres so many gameplays where even 13 works..... At least Jugg waves still works with 20. So far theres 2 reasons I find out why on Helli 12 didnt works. One is because sentry was above on first floor or on some spots 10 works and on some 12 or 13 works. I know I would get 200+ for sure with this camping spot for normal waves found by OneShot and Jugg and Helli strategy found by me. I even found pre set for clays but game said next time lol.
