I googled and saw that crossplatform co op on pc from steam to origin works, we tried and could not get it to work. My buddy picked up ds3 so I figured it was time to finally play it. It's brilliant, better than I remembered! I actually never played 3 for the same reason I never played Resident Evil 6, if you turn my horror into action you won't get my money. Once again: NO SAFETY GUARD ATTACHMENT! Your secondary weapon doesn't matter.I absolutely adore the first two games and with the remake of 1 on the way i'm doing a playthrough of ds2 and the game has absolutely aged like fine wine. I also underlined the most important parts with red. It took me a single minute to get the achievement, so it is far faster and less risky than getting slashed by necromorphs :) I have attached an image of the weapon used. I went to the start of Chapter 4 because there are no obstructions at all and as a bonus there is a bench next to you.

Team damage isn't enabled in the game either, so no danger to the guy who gets the achievement. He'll go down in a single shot even if you have an fully upgraded RIG and therefore this is the easiest solution. Then mash A asap and have your buddy shoot you again. This should bring him to low health at first and on the second shot bring him down.

All that matters is that his gun points at you. Trick is this: Have your co-op buddy stand infront of you and shoot his mine launcher into your face or shoulder, maybe a bit over you. I also did this after completing the game. IMPORTANT: Do NOT use safety guard! It makes this method impossible to use! I played on Casual difficulty, because you don't get gibbed as easily.

Upper tool tip is important because you want to not go into pieces when you shoot your partner. Hello TA! The simplest way is to build a completely new weapon with "Heavy Elite Frame" as frame, "Surveyor Charge" as Upper Tool and "Directed Ejection Field" as Upper Tool Tip.
