Grid inventory - Items take a rectangle of cells and turn with Rotate. Pockets, a belt with two pouches and a 4x3 satchel are always yours and never lost.

Packs and chest rig - Wear a Field Pack (5x4) or a Ranger Pack (6x5) in place of the satchel, and a Chest Rig with four pouches in place of the belt.

Workbench - A new base tab lays your gun on the bench to fit or take off its attachments, at once and for free.

Saved kits - Keep up to three kits on this computer and pack one with a key, or repack the last kit you deployed.

Weapon attachments - Two suppressors, a holographic sight, a 4x scope, a weapon light and a padded stock, each with a gain and a cost.

Field fitting - Fit an attachment from the inventory in 3 seconds. Taking damage or sprinting breaks it off.

Aim zoom - Sights zoom when you aim, and the 4x scope fills the screen with its own reticle.

Melee weapons - The Machete, Nail Bat, Fire Axe and Crowbar join the knife. The crowbar forces locks quietly and the axe breaks the tunnel's boards.

Heavy swing - Hold aim with a melee weapon to wind up a blow that hits harder and staggers, for more stamina.

Throwables - Molotovs set the ground on fire, pipe bombs beep to pull the horde in before they blow, and road flares burn red for a minute.

Armored infected - Its helmet and vest soak hits until they break. An axe blow, a heavy swing or a pipe bomb strips them.

Bloater - A swollen infected that bursts into a cloud of gas when it dies or reaches you. Wear a mask.

Situations - Something can happen during a run: a supply drop, a marked infected, a lost crew or heavy cargo, at most one per run and never the same one twice in a row.

Supply drop - A helicopter drops a crate of ammunition and supplies under an orange smoke column, and its first search draws a pack.

Marked infected - A tougher Brute or Armored infected and its escort, marked on your HUD, carry a plan you have not learned yet.

Lost crew - Two guarded bags left by a lost recovery crew, with their radio beacon still calling.

Heavy cargo - Carry an ammunition chest, a medical cooler or a generator home in both hands. You move slowly and cannot fight while carrying it.

Pickup card - A crew lost in the Forest leaves its handwritten notes for whoever finds them.

Main menu scene - The main menu now plays an extraction at dusk in the Forest, with ambience and no music.

Take-off - Extracting from a helicopter deck shows the lift-off before the results. Skip it after half a second.

Options screen - Graphics, audio, interface and controls on one page, applied at once, with presets from Low to Ultra.

New sounds - Melee swings and blunt hits, the molotov's glass and fire, the pipe bomb's beep and blast, the flare's strike, the heavy cargo and the Bloater's burst.

Ten new chapters - Fit the helicopter's range extension, then follow the trail into the Forest through chapters 14 to 23.

Installation jobs - From chapter 17, restart the Forest's machines: each works only while someone stays near it, and starting one draws a pack of infected.

Forest debrief - Complete chapter 23 to read how the reactor's last shift ended; both debriefs reopen from the Mission tab.

Optional objectives - Each Forest deployment offers up to two optional jobs, listed in the Mission tab with their site.

Supply activities - Industrial Area deployments can offer up to two optional supply jobs at sites whose campaign work is done.

Documents archive - The new Documents tab pins every banked record from both maps on the base's notice board.

The Forest - A second map of pine woods around a ranger station, a logging yard, a ridge lookout, a research annex and a hillside bunker, with three extractions.

Bunker depths - Two contaminated lower levels lead down to a research reactor still running with its cooling failed.

Bunker power - Throw the main breaker in the reception to light the bunker for the rest of the campaign.

Second insertion - With the landing guidance kit installed, the host can land the squad at the northern apron instead of the landing clearing.

Service Key - Craft a reusable key to open locked supply cases quietly, or force them open and make noise.

Research and Containment cards - Craft access cards for the annex reserve, the technical wing and the containment vault.

Loose finds - Each run lays supplies in the open on desks, shelves and crates: nine in the Industrial Area, twelve in the Forest.

Helipad mast - A red and white mast and a windsock beside the Industrial Area helipad mark the Entry extraction above the trees.

Overreach operators - Male and female crew members replace the s&box Citizen.

Radiation fields - Fields in the Forest raise your dose: warnings at 400 and 700 mSv, damage from 900, the dose falls again on clean ground.

Dose and air gauges - Two compact gauges above your health show your radiation dose, the air you breathe and your filter's remaining time.

Radiation effects - Inside a field, specks strike the camera, and colour drains from the view as your dose climbs.

Bolt-action rifle - A hard-hitting five-round rifle for long shots, crafted from plans in the bunker's technical records.

Clothing - Wear a helmet, vest, trousers and boots plus a separate mask.

Two clothing sets - Craft a combat set from Industrial Area plans and a radiation set from Forest records that slows your dose by up to 65%.

Radio - Switch on a radio in hand to talk to every squadmate with an enabled radio, anywhere on the map.

Radiation detector - A handheld dosimeter that shows the dose rate on its screen and clicks like a Geiger counter.

Level cap 40 - Three more levels, each with a skill point.

Four new skills - A new Hazards branch with Filter Discipline and Fast Recovery, plus Steady Hands and Follow Through.

Seven achievements - Added Rod Four, Clean Shutdown, Bare Skin, Hot Extraction, Long Shot, Holding the Crest and Old Hand, worth 155 points.

Living hangar - The lobby is now a 3D field hangar on a rainy night, and the camera moves to a different corner for each tab.

Hangar tab - Install permanent helicopter upgrades: the range extension opens the Forest and the landing guidance kit adds a second insertion.

Repack Last Loadout - Lay back the kit you deployed with last.

Helicopter arrival - Deploy onto the Industrial Area helipad with a skippable landing sequence.
