PS4 Resident Evil 5 Mercenaries United Solo Missile Area Wesker Midnight 150 kills

so after finally getting my 150 kills with sheva business in the mine. thought the powerful wesker character would be a cake walk in the mine. not quite, still have the same problem, ran out of time. went to the missile area, an easy stage in my opinion. still took me several tries, mainly because ran out majinis with plenty of time left. but this time, i got lucky, all the majinis showed up and didn't have to go look for them.
