Bleeding Edge

- From the Main Menu, Press "Fight"
This game is 4v4 and there are 2 different Modes:
- Objective Control: In Objective Control, teams fight to control 3 checkpoints. Whichever team can dominate two checkpoints wins
- Power Collection: Players race to collect Power Cells while vulnerable to attack. After collecting these, players then have to race to deposit Power Cells.

So technically you can do this on ANY match Type. And there is NO LIMIT on the amount that you heal per match. You can simply focus on healing on not killing at all to Grind this out fast.

There are 3 character classes. ONLY the "Support" class can Heal Teammates. As of Launch, there are 3 Support Characters:
- Miko: Press to use "Chain Heal" to heal a ally. *You can double tap it to HEAL YOURSELF!*
Miko also has a "Super" that heals allies with
- Kulev: Press to use "Sacred Ground" which summons a ward that heals allies in the surrounding area
- Zero Cool: Press for Healing Beam

Best Character to Use?!
ZERO COOL!
There is no Limit on the amount you can use your Healing Beam. If you prioritize Healing you should get 8-12k "Healing Points" Per Game. I recommend staying above your enemies and healing from an above platform. That way your not getting hurt, but constantly Healing your Teammates as they lose HP!💪

Keep using these Healing Methods until your Achievement Unlocks 😎🏆
VIDEO GUIDE:

I personally found that Kulev is by far the best character to use for healing. He is far more durable and has better abilities than Zero Cool. Kulev has a Ward ability that heals allies and damages enemies, he has a shield he can cast on himself, and he has an ability that makes enemies take 25% extra damage. All of these abilities are very useful in combat. With Kulev, I was consistently getting 10-15k healing per match. With Zero Cool, I was spending more time looking at the respawn screen than actually playing because he dies so easily. Zero Cool is pretty much a sitting duck as soon he gets hit. I was struggling to get 6k healing per match with him. Kulev is much stronger than the other healers at the time of writing this solution.

A few additional tips: don’t enter fights alone and stick with teammates as much as possible. If you fight someone in a 1v1 as Kulev, you are virtually guaranteed to lose the fight unless they already have very low health.

There are Two Maps on which you can make this Achievement easier.
• Aqueducts
• SkyGarden
On the Aqueducts Map (better known as the Sewer Map), Call a Friend of your Team and go to one of the Shock Walls. Remembering that your Character has to be ZeroCool and your Friend doesn't matter, I used Gizmo as an example.
Well, when you hit a shock wall, make sure your friend’s life is 100%. Now, your partner has to go through this "Shock Wall" and so he will take damage. Cure it 100% and repeat the process. Dare, Takes damage and Heals 100%, Simple. If I said an average on that map, I made about 20,000. Making him walk at least 10% in the Conquest.

On the SkyGarden Map, there are 3 Gongs, one at each point. Activating them makes the point on fire. Now, your friend will go to Fogo, and you will be healing with "ZeroCool".

Há Dois Mapas em que você pode fazer esta Conquista com mais Facilidade.
• Aquedutos
• Jardim Celestial
No Mapa Aquedutos (mais conhecido como Mapa do Esgoto), Chame um Amigo de sua Equipe e vá até uma das Paredes de Choque. Lembrando que seu Personagem tem que ser o ZeroCool e o seu Amigo tanto faz, usei de exemplo a Gizmo.
Bom, chegado a uma parede de choque, certifique-se que a vida do seu amigo esteja 100%. Agora, seu parceiro tem que atravessar essa "Parede de Choque" e assim tomará dano. Cure ele 100% e repita o Processo. Atrevessa, Toma dano e Cura 100%, Simples. Se eu falasse uma média nesse mapa, fiz uns 20 Mil. Fazendo que ande pelo menos uns 10% na Conquista.

No Mapa Jardim Celesital, há 3 Gongos, um em cada ponto. Ativando eles, faz que o ponto fique pegando fogo. Agora, seu amigo irá no Fogo, e você fica curando com o "ZeroCool"

I'm going to elaborate on Pedro's method as you can do this solo and get over 19000+ healing a game.

Aqueducts is the best map to boost this. If it doesn't come up play it out still as quitting can effect your matchmaking with other players.

Do the above the entire game hopefully people leave you alone and let you get on with it.

You need to use Kulev and use the following mods:

Medicament (increase sacred ground healing by 20%)

Prolonged Ward (increase sacred ground duration by 3 seconds)

Omen of Vigor (increase good omen shield health by 30%)

You also want to use the Bamboozle! Special if any enemies come bother you and are very close.

Take control of them and walk them into the electric gate and hopefully kill them and carry on with your healing.

Good luck!
