Hit 15 Helghast soldiers without reloading, using the secondary fire on the M66 SD Submachine gun

Please note that the M66 SD Submachine Gun is Luger's default weapon, so when you start her playthrough, you can begin farming kills for this trophy. However, you can also find the M66 on your regular campaign playthrough as other characters. Continue reading if you want to try your hands at the trophy sooner.

You will obtain your first M66 SD Submachine gun on the first level of the ninth chapter Hidden Pasts. Before you enter the ISA Missile Base, look to the left of the main gate. A poor ISA soul lies dead on the ground, but he has left this sweet gift for you. After picking up the weapon, you can look for ways to earn this trophy.

I suggest you continue playing through the first level as usual, and only attempt the trophy on the next one. This trophy may be a bit challenging on a Hard playthrough, so have patience. Use as much cover as possible, and only fire when you have a sure shot.

Start with a full magazine, and do not reload the weapon until you've earned the trophy. Remember to only use the secondary fire mode; you're only doing it right when you fire a supressed shot.
