PS4 Resident Evil 5 Mercenaries United solo Village Josh 150 kills

my on-going 150 kills challenge. actually this one i got 152 kills, my first ever 150+ kills. still haven't figured out the if there is a single melee can take out the giant majini. but from what i learned is close range 3 shot gun blasts will do. if not, then melee will take him out. i did good. only took 12+ minutes. if a mediocre player me can do it. so can you. i do recommend to get the chicken first before it starts running around. and you would hate to run out the clock just looking for the chicken for your 150th kill. it happened to me once.
