Tips for the "We'll call it a draw" achievement?

[GwenTheWitch]

What's the best way to shoot the arms off a hulk without killing it? Should I use a Railgun, Slugger, Scorcher, Anti-Material Rifle or something else?

Autocannon. It can take the arms off, but can't do meaningful lethal damage unless you hit the eye or the back.

Play some high diff you will likely be swarm by enemy when wait for extract tell your team mate before hand that you'll do achievement on the target you ping so they won't kill it use rail gun shoot both it's arms off and leave
I got it by accident tho

this. my friends and i just loaded up a lvl5 blitz, speedran it and extracted. youll almost always get at least 1 hulk at extract. just autocannon its arms off and youre good to go. if one doesnt show up by the time the ship arrives, just hang out till one does
