PS4 Resident Evil 5 Mercenaries United solo Missile Area Josh 150 kills

continue with my 150 kills mission. after getting my 150 kills in ancient ruins last night. i thought the missile area would be easy. well, it's easy, but not exactly a cake walk. simply because i don't know where the majinis will spawn during the final seconds. this path that i took at the end has worked for many characters. yet, i had one game that they spawn from below where the convey belt is. i thought that only happens during duo play? anyway, i got this 150 kills in less a day trying. killed my 150th with less than a second left.Sometimes luck is more important then skills. i suck and if i can do it, so can you.
