I recommend having some fun with this achievement, load it up on normal with two controllers or with a friend and have either the second controller or the friend do the work, you can also still get this achievement with zero multiplier skulls like bandana on, combine that with boom, grunt funeral and Sputnik and it’ll be fast, fun and easy
**Note** when doing the warthog jump have the person/controller that’s not getting the achievement to jump out of the hog right after the jump just in case of teleporting
