Cleaner is the title given to the group of survivors in the Back 4 Blood universe. These playable characters are immune to the parasitic outbreak and are fighting the undead to maintain the existence of the human race. Each protagonist features different traits, skills, and advantages, all of which enhance a players' experience and overall performance.

When gamers first play the latest co-op zombie gameBack 4 Blood, there are four default characters to choose from and four more cleaners to unlock after completing the first act. However, that doesn't mean the unlockable characters are any better than the default options. Each of the cleaners have individual attributes that gamers value differently based on their own play style.

8 Walker Deals More Damage & Rewards Players With Increased Accuracy

Walker is a versatile character with useful benefits for himself and his teammates. This cleaner should be considered by players who aim for a high kill count and want to get stuck into the action. He's also a good choice for players who are new to zombie survival games.

His impressive attribute is +10% damage making it easier to shoot down ridden compared to other cleaners. Any precision kills, such as headshots on common ridden or weak spot kills on special ridden, grant Walker +20% accuracy for five seconds. This gives him a steadier hand when aiming down sights and targeting enemies.

7 Hoffman Can Carry An Extra Explosive & Can Scavenge Ammunition

Back 4 Blood Hoffman

Out of the 8 cleaners, Hoffman is the gentleman wearing glasses and a body warmer. Many players believe guns, rifles, and pistols are the best form of protection in a zombie apocalypse game, but ammunition can be hard to come by.

With consistent hordes of zombies in Back 4 Blood, players must constantly be on the lookout for ammunition and other weapons whilst protecting themselves and their team. Hoffman's individual skill gives gamers a chance to find extra ammo from killed ridden, which he can also drop and share with other teammates. He also blesses players with an extra offensive inventory slot, which can be used to carry a second pipe bomb or molotov.

6 Jim Has A Quicker ADS Speed & Valuable Stacking Damage

Back 4 Blood's Jim

Jim is the ideal cleaner for those players who like to shoot from a distance and stay out of harm's way. Back 4 Blood allows players to add weapon attachments such as various sights to improve accuracy. With a customized gun and Jim's attributes, this hunter can be quite lethal behind the trigger.

Thanks to his character trait, Jim gets a damage increase for every precision kill. Jim can rack up a damage bonus of up to 50% which is lost after getting hit by an enemy. This character can also target enemies a lot faster with a +25% aim down sights speed increase.

5 Doc's Healing Abilities Benefit The Whole Team

This cleaner is called Doc for an obvious reason. She is another useful character to include on a mission because of her healing capabilities. Doc's skills and traits focus more on the team's health rather than her own benefits.

Doc's character trait allows her to heal the cleaners once each level. She uses her field dressings on other players to recover 25 health points, which is really handy if someone has low health and no support items. Her healing efficiency is also increased giving her character a +20% boost when using healing items.

4 Holly Has Heightened Damage Resistance & Replenishes Stamina With Every Kill

Back 4 Blood Holly

Another resilient cleaner is Holly, a kind-hearted lady with a positive attitude. After losing her parents, Holly learned to fend for herself after the "devil worm" plagued the population. She is the stamina class of the group allowing players to run for longer.

For each ridden she kills, Holly recovers 10 stamina points which is useful for avoiding danger and catching up with teammates. Her character advantage also gives her a 10% damage resistance to help maintain health when running through hordes. These additional stamina attributes make Holly a character not to be underestimated.

3 Mom Can Instantly Revive Downed Teammates & Carry More Bandages

As you might expect, Mom is the older lady in the group, and with age comes a great deal of experience. Mom is one tough cookie and both her team skill and individual trait will benefit everyone else playing. For this reason, she is always a good choice for any expedition into enemy territory.

When the cleaners are in trouble, Mom can turn it around and help downed players. Her individual skill lets players instantly revive incapacitated characters once per level. She can also carry an extra support item such as bandages, pain meds, and first aid kits.

2 Evangelo Regenerates Stamina Faster & Can Escape Enemy Grabs

Evangelo is the youngest cleaner in the group and is good option for people who like to abandon the rest of the group. Although players must work together to complete each level, Evangelo has some perks that will help get players out of tight situations.

Cleaners are often grabbed by enemies immobilizing players, which is especially annoying when there aren't any teammates around to help. Evangelo's individual skill allows him to break out of enemy grabs once every 60 seconds. He is also lucky enough to have a +25% stamina regeneration giving players a speedy and agile advantage.

1 Karlee Can Sense Danger & Warn Teammates

Perhaps the rebel of the group is Karlee, a self-made, independent woman who looks out for number one. She's a survivor with style and a dynamic personality which makes her an essential addition to the cleaners.

Her character skill benefits everyone as she can spot hazards and mutations and warn the rest of the team. Hazards include car alarms, security doors, and deep water. Karlee can also hold an extra quick item such as a defibrillator to resurrect teammates or a stun gun to prevent enemies from grabbing cleaners.
