PS4 Resident Evil 5 Mercenaries United Solo Prison Sheva Fairy Tale 150

so for the past 2 weeks trying to get the 150 kills in the mine, it was tough. i hate those dogs in the mine. so i went to the prison. different challenges. but i knew it was doable as i have done it with other characters before. and shava's hand cannon is great for the 5 executioners. one of the buggy problem i have is not able find the last majini. i have three 149 kills and plenty of time left. but this time i got lucky, they all showed up coming after me, and still got 27 seconds left on the clock.
