Official Maps List

KF-WestLondon	Most popular, good camping spots
KF-Farm	Open, tricky on HoE
KF-Offices	Tight corridors
KF-Foundry	Industrial, medium difficulty

Tips for Hell on Earth:

Team up. Solo HoE is extremely difficult.
Pick strong perks. Level 6 Support, Sharpshooter, and Demo are meta.
Camp smart. Find a choke point with weldable doors.
Save ammo for bosses. Patriarch is the real challenge.

Collectible Achievements (~40 total)

Hidden items scattered across maps that must be shot or interacted with.

KF-Hillbilly Horror: Gnome Achievements

KF-HillbillyHorror

Soul Collector — Free the souls of the 25 Gnomes hidden on Hillbilly Horror in one game.
Map achievements: Third Cousins, Second Cousins, First Cousins (Once Removed) and First Cousins for beating the map on Normal, Hard, Suicidal and Hell on Earth.

KF-Bedlam: Halloween Event Achievements

KF-Bedlam

Bedlam has no collectibles, but the first Halloween Horror event was built around it, and several achievements are tied to this map:

The Scene is Zed — Kill 250 Halloween Specimens in Bedlam.
This is No Ordinary Rabbit! — Kill 25 Halloween Scrakes in Bedlam.
Carving The Jack O' Lantern — Decapitate a burning Halloween specimen in Bedlam.
Sparkling in the Twilight — Kill the Vampire Patriarch Ringmaster in Bedlam.
Rule The Roost — Get all 6 achievements and unlock Commando Chicken.

KF-Moonbase: Z.E.D. Gun Pieces

KF-MoonBase

But It's All Red! — Collect all 16 Z.E.D. Gun pieces. Picking up all the pieces also unlocks the Zed Eradication Device for purchase at the Trader.
Tip: Moon Base has much lower gravity than other maps, so you jump higher and can propel yourself with shotgun blasts.

KF-Aperture: Golden Potato

KF-Aperture

Golden Potato — Get into GLaDOS' core on Aperture. The map has a heavily welded door that has to be unwelded first.
Map achievements: Science Got Done, Still Alive, This is a Triumph and I'm Making a Note Here, Huge Success for a Long game on Normal, Hard, Suicidal and Hell on Earth.

Per the killingfloor.ru forum thread "KF-Transit - ачивка 30 колбочек": there are 30 vials on both KF-Transit and KFO-Transit, and the thread came with videos showing every vial on both versions of the map. Many players look for the vials while playing through the objective mode. A tip from the thread: with headphones on, when there is no shooting and no monster screams, you can hear a distinctive bubbling sound near a vial.

Seasonal/Event Achievements (~50 total)

Originally available only during Christmas, Halloween, and Summer Sideshow events.

How to Unlock Them in 2025

Find an Event Server. Some servers run permanent "Christmas" or "Halloween" modes.
Use Mutators. In Solo, you can enable event Zeds via console commands or mutators.
Use SAM. If the event is truly impossible to trigger, SAM is the last resort.

Christmas Event Achievements

The Twisted Christmas 2010 list, per the "Achievements in the game" thread on the killingfloor.ru forum (2010):

Miscellaneous Achievements

Big Game Hunter — Kill 1000 Fleshpounds.
Slaughterhouse — Kill 10,000 Zeds total.
Surgeon — 10,000 headshots.
Survivalist — Survive 100 waves (across all games).
"Respect for the Dead" — kill 10 specimens that are eating corpses. Tips from the killingfloor.ru forum, "Достижение "Уважение к смерти"" thread: the players split up far apart (for example, opposite ends of Shopping Centre), one of them gets killed, and while the specimens eat the corpse the other shoots them from a distance, for example with the crossbow's zoom. If you come close, the specimens immediately switch to the living player. Another variant from the thread: on Biotics Lab one player runs a few meters ahead of the spawn, the second hides around a corner with no line of sight, the first dies, and the second rushes out with a shotgun once the specimens start eating. Players found that the kills often do not count, so it takes many attempts.
Uber Tuber — buy the potato for 70,000. Method from the killingfloor.ru forum thread "Картофелемет \ Uber Tuber": create a listen server on KFO-Fright Yard at Beginner difficulty, take the Berserker and get to the 3rd objective, where you have to stand on a platform to fill a bar. Do not step on the platform; instead kill the endlessly spawning zeds. For the author the farm took about 2 hours. Another member suggested farming on KF-Icebreaker by running Clots in a circle (a friend helps) and farming katanas and Desert Eagles; he added that the achievement also comes fairly quickly on Normal/Hard servers.
The Dwarfs?! axe backstab achievement (shown in the Russian client as «Вот мой топор») — kill 30 Fleshpounds with the Dwarfs?! axe using backstab (alternate) attacks. The method from the same thread's author: buy the Zed Gun Mk2, shoot the Fleshpound twice in a row with alternate fire to slow him down (he gets covered with a translucent blue mesh), and at that moment get behind him. Repeat 30 times.

Troubleshooting: Why Didn't I Get the Achievement?

Server Type Matters

Server Type	Achievements?
Whitelisted	Yes
Greylisted	Maybe (depends on config)
Blacklisted	No
Modded (custom mutators)	Usually No

Common Issues

Mutators Enabled: In Solo, enabling ANY mutator disables achievements (with few exceptions).
Wrong Difficulty: You must complete the map on the EXACT difficulty for the achievement. Suicidal doesn't count for Hard achievement.
Disconnected: You must be present from start to finish.
Server Crashed: No save. Achievement lost.

Bugged achievements

Source: killingfloor.ru forum, thread "Bugged achievements and how to deal with them", 2012.

Flea Circus (Abusement Park on Normal). Several players beat the map on Normal without getting the achievement, although the map's other difficulties unlocked fine. The bug had threads on the official Tripwire forum and the Steam forum; some players got the achievement, others got it neither solo nor in multiplayer.
Check the game length first. Map achievements only count for a 10-wave game; a common cause of the "bug" is playing a 7-wave game.
Hell on Earth does not count for Normal. Beating a higher difficulty does not unlock the lower ones.
Event maps outside the event. In 2012 players reported that on the Christmas Santa map neither achievements nor perk progress worked, on Bedlam and Aperture perk progress did not count, and on Abusement Park on Normal nobody on the server got the achievement. They guessed that after some update event maps only give progress during their own events.
Offline. One player finished a map solo while his internet was down; after reconnecting and Steam syncing, the achievement counted.
The Dwarfs?! axe ("Топор Dwarfs" thread on the killingfloor.ru forum): after you earn the achievement in Dwarfs?!, the axe and the achievement show up in KF with a delay. According to members' observations it ranges from a few minutes or hours to several days, weeks and even months; for one player the axe unlocked on wave 6-7 of Moonbase, which he started right after the Dwarfs?! achievement, while others waited half a year. Members put it down to poor syncing between the two games.
"Blow up 500 specimens with the M79". In the killingfloor.ru forum thread "Проблема с достижением "Разнести 500 мутантов с М79"", a player's progress bar did not move even after leveling Demolitions to 6. One participant completed it with the M79 in a solo game (on Farm, easy difficulty) after failing in multiplayer; another believed the description is wrong and got the achievement while shooting the M32.

VAC Ban? No. Valve does not VAC ban for SAM in Killing Floor 1.
When to use: Only close the game first. Never use SAM while connected to a server.

When to Use SAM

Broken achievements that won't trigger.
Seasonal events that are impossible to access legitimately.
Progress lost due to server crashes.
