How to Beat Infection in Guts & Blackpowder

Infection is Guts & Blackpowder's most punishing team-killer mechanic. Runners grab players, start a blight timer, and turn victims into hostile zombies if teammates fail to intervene. Infection modifiers amplify the threat across entire lobbies �?one missed save cascades into friendly shamblers attacking your barricade line from behind. This guide explains grab mechanics, melee save timing, Chaplain Blessing and Mercy abilities, and defensive positioning that keeps blight from ending otherwise winnable runs.

Every player should understand basic grab saves regardless of class. Chaplain specialists add Blessing prevention and Mercy cures, but DPS players who melee-save grabbed allies prevent more wipes than any single support channel. Master both layers: personal saves for pub lobbies, Chaplain coordination for infection-heavy campaigns.

How Infection Starts

Runners �?fast zombies introduced around wave seven in Endless and throughout mid-late Objective maps �?lunge and grab players on contact. A visible timer appears on the grabbed victim. While grabbed, the victim cannot shoot, heal, or build. The timer counts down toward full infection.

Teammates interrupt infection by meleeing the Runner or the grabbed player. Any melee hit resets or cancels the grab depending on timing. Musket butt strikes, Sabre swings, Axe cleaves, and Blunderbuss finishes all count. Ranged damage alone does not save �?you must close distance.

If the timer completes, the victim turns. Infected players become AI-controlled zombies attacking former teammates. Friendly fire rules do not protect you �?turned allies path toward the nearest barricade breach point.

Grab Save Fundamentals

Callouts save lives. When grabbed, shout immediately so nearby allies rotate. DPS players within five meters should abandon kill streaks and melee-save before re-engaging Shamblers.

Priority save order:

1. Surgeons and Chaplains �?losing support collapses sustain
2. Sappers mid-construction �?dead engineers mean no barricades next wave
3. Low-health DPS who cannot survive the grab duration

Each successful save earns roughly 5�?0 Francs and counts toward Soldier's Grace progress for Chaplain unlock. Farm saves deliberately in Endless past wave seven when Runners spawn consistently.

Chaplain Blessing

Blessing is Chaplain's preventive tool. Channel on allies before Runner waves to grant temporary infection immunity. Blessed players still take damage from grabs but cannot turn �?the blight timer never starts.

Timing matters. Blessing channels take seconds; casting mid-grab is too late. Pre-bless the firing line before holdout timers start on Leipzig cemetery or San Sebastian beach phases. Rotate Blessings across the team �?one Chaplain cannot maintain infinite uptime on twelve players.

Chaplains stand behind Sapper lines during Blessing channels, identical to Surgeon heal positioning. Read the team protection guide for safe support placement.

Chaplain Mercy

Mercy cures allies who are already infected �?mid-turn, timer nearly complete. The channel completes a full cleanse and restores the player to combat readiness. Mercy earns premium Francs (8�?5 per cure) compared to standard heals.

Mercy requires Chaplain unlocked via Soldier's Grace badge. If your lobby lacks Chaplain, melee saves remain the only option. Do not let infection complete hoping a Chaplain will arrive �?turn speed outpaces most Mercy reaction times in chaotic pubs.

Pair Mercy with Crucifix crowd control from the weapons catalog. Chaplain tools rank A-tier for infection utility on the weapon tier list during blight weeks.

Chaplain Infection Immunity

Chaplains cannot be infected. They walk through Runner packs that grab everyone else. Use this immunity to melee-save without fear of retaliatory grabs �?Chaplain is the safest grab-save class in the game.

Immunity does not mean invincibility. Bombers, Zappers, and Cuirassiers still kill Chaplains. Infection immunity solves one threat vector, not all damage.

Team Composition for Infection Weeks

When blight modifiers activate, shift roster toward infection counters:

• One Chaplain minimum �?Blessing before waves, Mercy for emergencies
• One Surgeon �?chip healing between grab events
• Two Sappers �?barricades prevent Runners reaching backline supports
• Remaining Infantry and Seaman �?melee-capable DPS for saves

Avoid clustering. Zappers chain lightning through grouped players; infection panic makes clustering worse. Spread the firing line along barricade segments with two-meter gaps.

Infection on Campaign Maps

London and long Objective chains punish teams without infection answers. Sewer segments and vat house finales combine Runners with tight corridors �?ideal grab ambush terrain. Queue Chaplain when running London badge attempts or Madcaps chain progression.

Endless infection spikes after wave seven. Pre-position melee DPS near barricade gaps where Runners slip through. Officer Charge buffs help Sappers melee-save while armored in Siege Engineer gear from the Sapper build guide.

Common Infection Mistakes

• Shooting grabbed allies with muskets instead of melee-saving
• Letting infection complete because "someone else will save"
• Blessing after Runners already grabbed half the team
• Clustering during Zapper waves �?double wipe from chains plus grabs
• Skipping Chaplain on London runs with active blight modifiers
