Killed the Heavy using the StA-14 rifle


Chapter 7 Scrapyard Shortcut Blind Yards, immediately after the area as described in Power Spike trophy above, youll come to a large yellow structure on your right and an ammo box beside a weapon rack containing the StA-14. Grab this while you can because shortly after you move forward a cutscene dialogue between Rico and Jammer will play, followed by your first encounter with a Heavy.

The Heavy is a heavily armored Helghast with a chaingun. The weapon rack is blocked after the cutscene so youll have to restart the section if you didnt grab the gun prior to the cutscene. Aim for the Heavys head a few times to make him turn around, and quickly shoot the horizontal red canisters behind his back. Repeat this a couple of times and youll take him down.
