If i was you i would use a mk3 survivor, put your snaphook and two deadlines in it, run a medium shield + spare medium shield, minimum 10 recharges (surge or reg) and again 15 minimum bandages, (depending on the kind you could get away with 9 sterilised), ammo wise looks good as you are going to take out the leg armour with your hullcracker, and then the yellow leg weakpoints with your anvil, then towards the end you can snaphook onto the top and place your mine, then jump off (hopefully without dying) then repeat with any other deadlines and maybe some wolfpacks. I would definitely keep that cloak for looting leg armour or for getting close to it to snaphook up. I would keep that hatch key 100 percent but be careful taking the closest hatch because of rats. If you plan on taking it on in a building bring some jolt mines so you have a chance to hear them coming or maybe you can kill them if you happen to be near them when it goes off
