How to crouch

1. Press C (default binding named Sneak / Crouch in the options screen).
2. Move with WASD while crouched to sneak at a lower profile and reduced noise.
3. Press C again to stand.
4. Optional: hold Run (default Left Shift) while crouched for a crouched run—faster than a crouch-walk, still louder and more tiring than standing still or slow sneak.

What crouching does

• Lower visibility — you present a smaller profile; zombies are less likely to spot you at the same range as when standing.
• Lower noise — footsteps and movement are quieter, which pairs with the Sneaking and Lightfooted skills over time.
• Higher Endurance use — sneaking uses slightly more energy than walking. Long crouch-walks or crouch-runs drain stamina faster.
• Not invisibility — crouching does not stop the undead from seeing or hearing you if you get too close, make noise, or leave cover.

Crouch vs Aim / Strafe

These are different controls. Crouch is the Sneak toggle; Ctrl or right-click is Aim, and moving while aiming is Strafe—not a second crouch key and not a Sneaking XP shortcut.

Cover that helps

Crouching alone helps; cover multiplies it. Use these for a lower profile while sneaking:

• Walls — stick close to walls while sneaking; your character crouches lower and is harder to spot.
• Short fences — sneak beside short fences for the same lower profile bonus.
• Vehicles — crouch next to cars and trucks to break line of sight and drop visibility further.

Sneak Stab (stealth kill)

When you need a silent takedown rather than a shove fight:

1. Equip a knife (or other valid stealth knife-type weapon).
2. Crouch and approach from directly behind the zombie.
3. Hold Aim (Ctrl or RMB) and move into position—your character’s hand raises when the stab is ready.
4. Attack once the arm is up. Done correctly, the kill is quiet compared to a full melee swing.

This is high risk at close range. One turn or a second zombie in the cone of vision ends the sequence fast.

How Sneaking skill XP works

Crouching next to a wall does not by itself level Sneaking. Cover only improves concealment while you move.

• Need presence, not empty streets — Sneaking experience is earned by moving undetected when zombies are close enough to potentially notice you. Practicing crouch-walks in a cleared field with nothing around grants little or nothing.
• Stay undetected — once you are spotted and the chase starts, you are no longer “sneaking past” for training value; break contact or clear the threat before trying again.
• Cover supports training — walls, short fences, and vehicles make it safer to stay near groups without being seen. They are concealment, not an XP source by themselves.
• Related skills — quiet movement also feeds into Lightfooted over time. That skill shrinks the footstep radius zombies can hear; it is not the same as the crouch toggle.
• Sandbox multipliers — custom games can change Sneaking / Lightfooted / Nimble XP rates; defaults differ from boosted sandbox.

Useful traits (optional)

Quick checklist

• Toggle crouch with default C (rebind Sneak if needed).
• Expect lower noise/visibility and higher Endurance drain.
• Use walls, short fences, and vehicles for a lower crouch profile.
• Do not treat see-through fences as solid cover.
• Treat Ctrl / RMB as Aim → Strafe when moving, not as crouch.
• Train Sneaking near zombies while remaining undetected—not by AFK crouching against a wall.
• For silent kills: knife, behind target, Aim until the arm raises, then strike.
