Here are the four ways you'll need to revive someone to unlock the achievement.
1 - Normal revive
Simply revive someone to get this (Get a friend to down himself, being crushed by a Giant, getting hit by a Zombie or cooking a Grenade will all work.)
2 - Quick Revive
Revive someone while you have the Quick Revive perk on you.
3 - Maxis Drone
There are three pieces to build this, once built, get a friend to go down, and then hit down on your D-pad to activate the Maxis Drone once you've picked it up, it will then revive your friend if you are close enough. (This will also shoot zombies so make sure to be away from a crawler if you don't want the next round to begin)
4 - Ultimate Staff Revive
Build an ultimate staff, then hit left on the D-pad to select a healing rod out, shoot it at your downed teammate.
- Building the Ultimate Wind Staff -Wind Staff Parts
There are three giants that walk across the map. On each of the giants, there is a secret entrance which leads inside the giant where you can claim your staff part. To open this up you'll need to shoot under ONE of the giants feet, there is some white markings, shoot them with any gun (Burst fire is recommended) and it should open up a white portal in his foot. You then have to stand where he lands that foot to be taken inside the giant where you can claim your part. (It's better to shoot this as soon as he appears from a safe distance then move to another section where he may stand). It's better this way because if you try shooting it when it's right over you and you miss, you'll go down. Squish.
Be careful not to shoot the wrong foot either as the portal only appears on ONE of the giant's foot.The Music Box
Now once you've gotten all the parts, you'll need to go into the Pack-A-Punch area and go down the stairs, right to the bottom which is where you'll find the music box. Place the box on the table which will open up some more stairs leading to a new area.
At the bottom there will be four coloured statues, the same as the staffs.
Now you must collect an element for each staff.
There are four cave systems around the map which you can go through, they always lead to a dead end and are labeled - Ice (Blue), Fire (Orange), Lightning (Purple) and Wind (Yellow). For example, if you have the yellow disc, you'll go to the Wind tunnel.
The yellow (wind) coloured disc is in the Generator 5/Staminup area.
You then put the music box on the table, the disc will be automatically selected and will slowly open up a portal which will take you to the 'Crazy Place'. From here, move forward and go to a small coloured alter, which you'll be able to take an element from. You can only hold one at a time so mulitiple trips through each portal will be required. For those wondering, you need to use the specific caves to pick up the specific elements, you can't pick up the Fire element by going through the Ice portal.
Go back to the statues and build the staff. Don't waste ammo, you need if for the next few wind puzzles.
- Enter the Crazy Place, any portal will do.
- Search for the Yellow zone and look up to find the puzzle
- Follow the next steps in order to unlock the first Ultimate staff
You'll need to shoot the four tiles with the Wind Staff only, to match up to what they look like in this video. Take your time! You have limited ammo so don't go wasting too much of it.

Once done Samantha will speak to you, and the tiles should move a little bit indicating that the challenge is complete. You are halfway there.
Now, you must go back outside and shoot THREE metal ball type things (It's hard to describe what they are)
The 1st right next to the Juggernog generator. Stand in front of the Random perk bottle machine (It costs 1,500) and look forward. You will see the metal gong thing on a bit of land just before the next area where the giant's foot lands. Shoot it with the staff twice (Another time just in case you miss and don't realise it)
The 2nd one appears near the Staminup generator. You'll need to be on the far left of the map when you run to this area so you'd be running right past the soul chest. (The chest you fill with souls as part of the challenge which you get rewards from.)
BEFORE you get to this chest, but SLIGHTLY after you walk past a burning cart, look to your right on the piece of land and you'll see the second gong, shoot it and prepare for the final one.
The final one is on the way to generator 6, which is at the church. Open up the pathway to Church zone, and you'll be approaching where the giant's foot lands and also where a soul chest is. before you get to the top of those mini stairs, look right and search along the graveyards in the distance, you'll come across the final gong in the distance, shoot it twice and you should finally hear Samantha speak to you.
- Arranging the discs -
Before moving on, switch all the discs below the pack a punch area using the controls so that all the colours are YELLOW. Then shoot the yellow orb that will appear with the staff.
- Put the Rod back where you took the original element (Yellow Alter in Crazy Place)
- Fill the staff with zombie souls
- Take the staff once Samantha has spoken and the 1st Ultimate Staff is yours, enjoy.
Zombie Blood does not count towards this achievement and the Ballistic Knife does not appear on this map, so you can't Pack a Punch is and revive someone with it.
All four revives need to be done in one game.
