You get your friend to setup an auto turret facing the wall and stand next to it while you (the alien) attack with whatever ability is required for the challenge. If you kill the marine AND the turret it counts as a double kill...

I can confirm that you can do this challange in bug hunt mode.
24- Mercy Killer: Use the Combat Pistol to kill 5 enemies that were covered in fire
Be warned you can not complete the challange that requires you to kill 25 Aliens with claymores in Bug hunt mode.
