PS4 Resident Evil 5 Mercenaries United solo Ancient Runis Josh 150 kills

continue with my 150 kills challenge. this one took me about 5 days, an hour every night to finally get it. i have had many 146+ with time left on the clock but not able to find the last few majinis. i took the same path everytime, but with a little luck all the majinis showed up with 4 seconds left on the clock. this map is not large, but the bonus timers are spaced quite far apart. several times i paid no attention to the 30 seconds warning and then i failed to reach the next timer before clock ran out. o also learne that with this map, you have to keep going forward, do not turn back to kill a couple majinis. because the map is large area and you could be wasting precious time. unless you are those youtubers pro gamers. but then again, i'm just a mediocre player trying to get the 150 kills milestone in every map (except the experimental facility),

missile area is next.
