Back 4 Blood Weapons Guide: Best Weapons Ranked

Q: How many levels are in the campaign?

Thirty three missions, arranged as four Acts and ten chapters. Act 1 has 13 missions, Act 2 has 10, Act 3 has 9 and Act 4 is a single long boss level called The Abomination. Later expansions added further Acts on top of that.

Q: Does deck order really matter?

Yes. Decks are drawn in the order you arrange them rather than shuffled, and you take one card per level. A card sitting at position 12 will not be in play until deep into Act 2, so the fix for your weakest area belongs in the first few slots.

Q: Which Cleaner is best for a new player?

Doc or Mom. Doc raises healing efficiency and gives the team +25% Trauma Resistance, and Mom gives the team one extra life plus an extra support inventory slot. Both cover the mistakes a new team actually makes, rather than adding damage nobody is missing.

Q: What are Corruption Cards?

Cards the Director plays against your team before a level, changing conditions rather than raising numbers: added specials, fog, mutations, timed objectives and environmental hazards. They are displayed in the safe room beforehand, so they are meant to be read and prepared for.

Q: What is the difficulty order?

Recruit, Veteran, Nightmare and No Hope, with No Hope added in April 2022 alongside the Tunnels of Terror expansion. Nightmare and above pay noticeably more supply points, but they assume a finished deck and four Cleaners covering different roles.

EarlyGuides Editorial Team

Researched and editorially reviewed. Updated August 12, 2026.

Back 4 Blood is Turtle Rock's four player co-op shooter about eight Cleaners holding out against the Ridden from a base called Fort Hope. The campaign runs 33 missions across four Acts and ten chapters, and the part that separates it from the studio's earlier work is the card layer: you bring a 15 card deck, draw one card between levels, and the game's Director answers with Corruption Cards that change the level you are about to play. Difficulty runs Recruit, Veteran, Nightmare and No Hope, and by Nightmare a deck that does not match your role is the reason runs end.

Your choice of weapons defines your damage output and playstyle. This guide ranks every major option, explains what makes each one strong, and tells you which builds they pair best with.

Weapons Rankings

Weapon	Tier	Best For	Notes
AA12	S	Shotgun decks running Rolling Thunder, and any Cleaner assigned to hold a chokepoint.	A fully automatic shotgun and the strongest close range answer in the game.
M249	A	Holdout objectives and horde events, especially with a teammate covering specials.	A light machine gun with the magazine capacity to fight a full horde without a reload window.
Phoenix 350L	A	Marksman decks and any level where a Corruption Card has stacked extra specials.	A sniper rifle that kills most specials with a single weak point hit.
Ranch Rifle	B	Players who want precision damage without giving up close range viability.	A semi-automatic rifle with good accuracy and manageable recoil, which makes it the practical middle option between an assault rifle and a sniper.
Uzi	B	Second weapon slots under Two Is One and One Is None, and support players conserving heavy ammo.	A submachine gun with a high rate of fire and light SMG ammo that is rarely contested by the rest of the team.

S-Tier: AA12

A fully automatic shotgun and the strongest close range answer in the game. It clears a doorway of common Ridden in one burst and it stops a Tallboy that reached the team, at the cost of eating ammo faster than the safe room can refill it.

Tier	S
Best For	Shotgun decks running Rolling Thunder, and any Cleaner assigned to hold a chokepoint.
Key Mechanic	Fifteen card decks
Recommended Role	Walker

How to get it: Available from mid-game onward. See our walkthrough for the exact progression point.

Best builds using AA12: Pairs naturally with Walker thanks to how their stat scaling lines up.

A-Tier: M249

A light machine gun with the magazine capacity to fight a full horde without a reload window. It is heavy and slow to aim, which makes it a horde weapon rather than a special-killing one.

Attribute	Detail
Tier	A
Best For	Holdout objectives and horde events, especially with a teammate covering specials.
Key Mechanic	Corruption Cards
Recommended Role	Holly

How to get it: Accessible in the early-to-mid game. Check our maps guide for the location.

A-Tier: Phoenix 350L

A sniper rifle that kills most specials with a single weak point hit. Paired with Ridden Slayer and Jim's weak spot bonus it removes a Hag or a Snitch before either becomes a problem for the team.

Attribute	Detail
Tier	A
Best For	Marksman decks and any level where a Corruption Card has stacked extra specials.
Key Mechanic	Trauma damage
Recommended Role	Doc

B-Tier: Ranch Rifle

A semi-automatic rifle with good accuracy and manageable recoil, which makes it the practical middle option between an assault rifle and a sniper. It is generous with ammo, so it holds up on levels that punish overspending.

Attribute	Detail
Tier	B
Best For	Players who want precision damage without giving up close range viability.
Key Mechanic	Copper and safe room buys
Recommended Role	Mom

How to get it: Found in later areas. Our walkthrough covers when you can access this.

B-Tier: Uzi

A submachine gun with a high rate of fire and light SMG ammo that is rarely contested by the rest of the team. Weak per shot, so it works as a secondary alongside a sniper rather than as a primary on Nightmare.

Attribute	Detail
Tier	B
Best For	Second weapon slots under Two Is One and One Is None, and support players conserving heavy ammo.
Key Mechanic	Special Ridden and hordes
Recommended Role	Jim

Weapons Progression Path

The order you should acquire weapons as you progress:

Starting gear → Enough to clear Fort Hope
M249 → Your first real upgrade, available early
Phoenix 350L → Mid-game upgrade with good scaling
AA12 → Best-in-slot, aim for this by late game
Upgrade to max → The power spike from max upgrades is enormous

Weapons Tips

Always upgrade your primary weapon before diversifying. One strong option beats three mediocre ones.
Match your weapons to your build's stat priorities for maximum scaling.
Deck order matters more than deck contents because cards are drawn in the order you set, never shuffled. Put Combat Knife, Cross Trainers or whatever fixes your biggest weakness in the first three slots, since a card at position 14 arrives in Act 3 at best.
