How to Get Every Badge in Project Lazarus ZOMBIES

Project Lazarus ZOMBIES tracks progress with Roblox badges, not promo codes. There is still no redeem box as of September 2026. Badges fire from in-match actions: a wall gun, a Mystery Box spin, a Pack-a-Punch, cassette tapes, and surviving to round 50. This page is the checklist. Pair it with Getting Started for the first power route and high-round strategy for the ultra.

The game is online co-op for up to six. You can earn most badges in a public lobby. Round 50 and the tape hunts are cleaner in a private server so randoms do not train through your cassette room.

Combat badges you can finish by round 13

Lock and Load pops the first time you buy a wall weapon. On Graduation that is the B93 Raffica or the SKS/Ranger for 500, or the library MP5 for 1,000. On Research the office M14 or stair Raffica does it. Do not wait for a box gun.

The Box pops when you spend 950 on the Mystery Box. Wait until power is on and Frostbite can actually roll (round 6+). A Joker refunds the 950 and still counts as using the box.

Upgrade pops on the first successful Pack-a-Punch. That is 5,000 points plus the Graduation key/harvester or Research’s four consoles. Do not punch the starter Beretta M9. Full steps live on How to Pack-a-Punch.

Round 10, 20, 30, and 40 badges fire just by staying alive. They stack during a single run. You do not need a new lobby for each.

Project Lazarus: How To Get All Badges Guaranteed

Graduation tape badge: When Something Is Gone

This Easter egg is two cassette tapes on Graduation. Locations can shuffle after patches, but the classic pair is:

1. The classroom next to the stairs — tape on the front-left of the room.
2. The Speed Cola room — tape on a bench.

Interact with F. The song is titled When Something Is Gone. Grabbing both awards the badge. Do this after power is on so you can walk the school without a three-hit down ending the hunt. Leave a crawler in the hall if you are solo.

A dedicated clip of the hunt is easy to over-index on; the all-badges route in the embedded video still walks Graduation after Research and picks the last tape in a room most players skip. If a tape is not on the bench, sweep every classroom, the library, and the nurse wing before you assume it despawned.

Research tape badge: See You In Hell

Research asks for four cassettes. They spawn at random set points across offices, the testing chamber, labs, and corridors. Unlock the map first — you cannot collect a tape behind unbought debris. Hold F on each tape. Comments on older tutorials note logitech101 has moved spawns before; treat any one YouTube timestamp as a hint, not a GPS.

Research also has DEFCON panels on the way to Pack-a-Punch. Divert the four green consoles so the under-stairs machine lights. That is the Upgrade badge on this map, not a separate Roblox badge.

Round 50

The ultra. A tiny fraction of the 216 million visits have it. Requirements in practice: full map, four perks (Juggernog and Double Tap first), a Pack-a-Punched wonder weapon, and a wide train. Graduation’s library is the proven loop. Research players freeze chokepoints with Frostbite. Details and ammo rules are on high-round strategy and how to train.

You must be in the match from the start for some badge checks. Joining mid-run can skip Round 50. Do not AFK in the storage closet and expect the badge to credit.

One-session route (Research first, then Graduation)

EdgeMaster’s 2025 route still works in 2026 after the Model 1887 patch:

1. Research: wall K1A, Double Tap, open labs, tapes and DEFCON while farming, Pack-a-Punch, box for Frostbite or Ray Gun, train to 50.
2. Reset. Graduation: wall MP5, power, key, perks, punch, remaining tapes, library farm to 50 if you still need the ultra.

Lock and Load, The Box, and Upgrade should be done before you ever think about round 30. The tape badges are the ones people leave for “later” and then wipe at 22.

No game pass is required. No code exists to skip a badge. The easter eggs page covers the Maverick and Whizzbanger toys that sit next to the tape songs. Use this page as the stamp list, then go play the round.
