Getting started: side, class, and look

Step

In short Pick your side and class before anything else — everything else builds from that choice.

When you first load in, you choose between the USA and Germany. After that, you pick a class that suits how you want to play. The game also lets you save a separate look for each class and nation, so you can customize without losing your setup.

Choose a side decide between the USA or Germany before the round begins.
Open your inventory the Customization Update added 30+ cosmetic items including hair, beards, scarves, and glasses, all buyable straight from your inventory.
Save your look the game stores a separate appearance for each class and nation combination.

How objective maps work

Tips

In short Objective maps have specific goals beyond surviving waves, and clearing them on any difficulty earns you a badge.

Two maps — Normandy and Battle of Brest — work differently from standard wave defence. Each has a goal you must complete to escape, and finishing either one rewards you with a badge regardless of which difficulty you chose.

Tips worth knowing

Both Normandy and Battle of Brest can be completed on any difficulty.
Clearing Normandy earns the Triumph Normandy badge; clearing Battle of Brest earns the Triumphed Battle of Brest badge.

Kill-count badges and how progress saves

Summary

In short Your total zombie kills carry over between sessions, so every kill counts toward the next badge even if you log off.

There are eight kill-count badges, starting at 50 kills and climbing to 50,000. Because the game saves your cumulative total, you can chip away at these across many sessions without losing ground.

Recruit　50 total zombie kills
Frontline Soldier　250 total zombie kills
Battle-Hardened　1,000 total zombie kills
Veteran of the Dead　2,500 total zombie kills
Undead Exterminator　5,000 total zombie kills
Frontline Reaper　10,000 total zombie kills
Harbinger of Extinction　25,000 total zombie kills
The Last Man Standing　50,000 total zombie kills

Rules that can get you banned

Warn

In short Breaking the game's rules can result in a permanent ban, so know them before you play.

The Undead Frontline enforces a clear ruleset. Because it is a co-op game, behaviour that disrupts other players is taken seriously.

Worth watching out for

Using exploits or abusing glitches results in a permanent ban.

Toxic behaviour or inappropriate chat will get you removed.

Griefing teammates or deliberately stalling a round is also a bannable offence.

Misusing the report system against other players can itself lead to a ban.

All standard Roblox Terms of Use apply on top of the game's own rules.

Glossary

Objective map: A special map type with a specific goal — such as escaping — that must be completed to earn a badge, as opposed to standard wave survival.
Wave: A single surge of zombies that the team must eliminate before the next group arrives.
Class: The role you select at the start of a session, which determines how you contribute to the team.
Reputation: A progression measure that increases as you keep playing.
Karl's truck: The vehicle on the Normandy objective map that must be repaired using three collected parts before you can escape.

Common questions

FAQ

Do my zombie kills reset when I leave the game?

No. Your total kill count is saved to your account every time you play, so you can log off and come back without losing progress. All eight kill-count badges can be earned across as many sessions as you need.

Can I get the Scavenger badge while playing with a full team?

You can be in a team, but every part of the task has to be done by you alone. All three truck parts must be collected and delivered to Karl by you yourself.

Do I have to play on a high difficulty to earn the objective map badges?

No — both the Triumph Normandy and Triumphed Battle of Brest badges can be earned on any difficulty.

Are private servers really free?

Yes. The game offers private servers at no cost, and they come with admin commands included.
