I nearly threw my controller off the wall a few times whilst doing this Typically I would play safe, build my super (Stormcaller) equip TLW and run into a Sunbreaker and get shut down Trick is to stay calm, pick your encounters, don't use TLW until you get Super and heavy ammo. What I ended up using to finish the quest was play control keep my super until heavy ammo dropped, equip TLW, zoom over to enemy heavy spawn pop Super = multi kills Grab Heavy = more multi kills Didn't take me more than 3 matches to go from 50% to 100% doing this
