Controls

Project Lazarus ZOMBIES is a released Roblox co-op shooter with a short bind list. You do not jump. You knife, sprint, board, and interact. A wrong bind is a three-hit down and a 45-second bleedout while the squad hunts for the prompt. Learn the keys before you spend 2,500 on Juggernog.

This page is the input sheet. Getting Started is the spend order.

Default PC and gamepad binds

Interact is a tap on keyboard and a hold on a gamepad because the same face button also reloads.

Move with WASD. Jumping is disabled. If you keep tapping space, you are wasting the moment you should have started a loop. Read how to train zombies once sprint feels automatic.

Knife (V) and sprint (Left Shift) print points and save lives. A knife kill is 130; a headshot is 100. Rounds 1-5 should be mostly stabs. Later, sprint is how you keep 24 zombies in a line.

Mobile and touch

Phones get on-screen fire, ADS, reload, interact, knife, swap, and a thumbstick. Interact is easy to miss when a revive and a wall buy overlap. Open settings and pick a mobile custom layout so interact is not under your fire thumb. Move knife to the right side. Six-player mobile lobbies wipe when two people cannot find F while someone bleeds out.

Settings worth changing before round 1

Press P (D-pad down) in the lobby, not mid-train.

  • Mute licensed music if you need window breaks and the Pack-a-Punch harvester cue over the school bell.
  • Toggle aim if holding LT or right mouse fights sprint. Default is hold to ADS.
  • Reload / Interact on controller: Tap to Reload (hold to interact) is safer. Prioritize Interact if you reload inside a revive prompt.
  • Button B can be previous weapon or melee. If right-stick click already knifes, leave B as swap so you do not melee the Ray Gun.
  • Bumper equip lets LB / RB cycle guns, useful with Mule Kick.
  • Swap LB/RB with LT/RT only after a private-match test. Reversed triggers in a public six-player game are a down.

Scoreboard (Tab) shows who is broke. Check it before you open a 1,000-point door the lobby cannot follow.

How the binds play in a real round

You hold F to flip power, grab the Graduation silver key, feed the harvester, divert Research consoles, board windows, and revive. For boards, tap once and stay in range; you can reload or knife while planks go on. That 10 points per board caps per round, so do not stand in a window when the horde is already inside.

ADS is for 100-point headshots and for not dumping a packed magazine into a wall. Hip-fire is fine on round 3, not on a six-shot Frostbite. Inspect (B) is vanity; never inspect in a doorway.

Slots are 1 and 2 until Mule Kick adds a third. Number keys beat the scroll wheel when a crawler is on your hip. A down deletes perks and the third gun, so slot 3 is gone after the revive.

Practice order

Host private Graduation. Round 1: knife and boards only. Round 2: ADS headshots. Round 3: a small spawn loop that does not hug a window spawn. Then open doors toward power using Getting Started. When you can knife, board, and sprint without looking down, spend on perks and Pack-a-Punch.

Public lobbies will not wait for you to find F. If someone is looping the library, do not cut their train. That is how you both go down and the bleedout clock starts for the squad.

A clean bind setup will not get you the round 50 badge by itself. It will stop the cheap downs that make high-round strategy irrelevant. Set P, confirm interact is not fighting reload, put knife where your thumb can find it, and then play the map instead of fighting the HUD. The zombies do not care that you usually jump.

FAQ

Frequently Asked Questions

Quick answers for perks, Mystery Box pulls, and high-round survival.

What is the interact key?

F on keyboard, hold X on a gamepad. Use it for doors, perks, the box, boards, power, and revives. On controller, hold to interact and tap to reload unless you change settings.

How do I aim down sights?

Q or right mouse on PC, left trigger on a gamepad. Toggle aim lives under settings (P) if holding the button fights sprint.

Can I jump or slide?

No. Jumping is disabled. Movement is walk, sprint (Left Shift / left stick click), and the loops in how to train zombies.

Why do I reload when I try to revive?

Gamepad X is both reload and interact. Open settings with P or D-pad down and set Reload/Interact to hold-to-interact, or move on mobile so the buttons do not overlap.

When should I open settings?

In the lobby or between rounds, never mid-train. A paused thumb on round 28 is a down, and downs delete perks.
