PS4 Resident Evil 5 Mercenaries United Solo Prison Sheva Business 150 kills

after 4 nights of trying to get 150 kills with sheva business in the mine and missile area, no luck at all. kept running out of time. got a little down, so went to try at the prison for a change of scenery. well, it only took me like 4 or 5 tries to get the 150 kills. the prison might be hard with weak weapons. but it actually easier for 150 kills with the reunion characters than the mine and missile area. my opinion.

oh, just ran out of magnum ammo right before the last majini. luck helps too.
