Weapon skins

Get ready to bling out your guns! With new skins and charms for your weapons, find your favourite combinations of charms and skins. You are now able to customize all of your guns to your liking!

Launch the game before August 31. and get a free crate where you can choose a skin or a charm for free!

How it works

A crate dropped once per day. After 15 minutes of gameplay, the crate will drop once you complete a heist!

Crates can also be bought and sold on the community market. Once you own a crate, you can open it and select a skin or charm to purchase using heist coins. These skins/charms can not be traded or sold.

A new “Crate” tab has been added to the top bar in the main menu, here you can find and open your crates.

Once you have a skin you can go to the “Loadout” tab and you will see a “Cosmetics” button underneath each weapon. Press it and you will be able to see your skins and charms. A handful of skins can also be bought without a case. These are also shown in the “Cosmetics” menu.

Once you own a skin/charm it can be used on any weapon, and multiple weapons at the same time!

Postal office

Get ready to sneak in and leave without a trace, in the new postal office map.

The heist takes place in a postal office depot, just in time before a valuable shipment of jewellery leaves the bay. Sneak into the postal office, maneuver around security, locate and break into the trucks using the password, before they go out for delivery.

From One-armed robber

Get your best equipment ready, because there is a new heist in One-armed robber. The Harbour Heist!

A new shipment of missile guidance chips and military equipment from Rodman has just arrived in the shipping yard. Find and break into the containers and escape with the equipment.

This heist takes place at night during a thunderstorm, breaking into the containers is not as easy as it might seem. Rodman doesn’t mess around when it comes to security. Inside each container is a lasergrid, to disable it you will have to find the password. And don’t even think about breaking into the container before you disable the alarm, otherwise you’ll be in trouble!

Grenades

Not only do we have a new heist for you, we’ve also got some brand new equipment for you to try out: Grenades! Three kinds of grenades, each suited for a different playstyle and heist!

Fragmentation grenade

The classic fragmentation grenade. Pull the pin and throw it, and it will blow up anything or anyone nearby when it goes off. But don’t try to pick it up after you’ve thrown it, once that handle flies off there’s no way to stop it from exploding, and you only have 3 seconds to get away!

Distraction grenade

Is there a guard that’s always in your way? And do you wish you could just make him go away, but you are just not able to take him out? Try the distraction grenade! Activate it, toss it, and a nearby guard will come and check it out. It will keep him distracted for a good 30 seconds.

EMP grenade

This grenade sends out a powerful electromagnetic pulse that will disrupt nearby electronics for 30 seconds. Use it to get past security cameras, disable lasers, or temporarily pause guard phones’ countdown.

Other explosives

In addition to the grenades we have also added explosive gas canisters, these are scattered around maps. Check out the Harbour heist to get an idea of how it is used, and will be used in the future!

Santa outfit

Get in the Christmas spirit with the Santa outfit and matching hat & beard! Available until December 25.

Map sale

All maps are on sale for the duration of the Steam Winter sale!

  • Add patrolling guards as security threats to avoid

From One-armed robber

Step into the action with the latest map for one-armed robber: the Mansion Heist. The heist takes place during the millionaire owner’s extravagant birthday party, where he’s celebrating his latest indulgence—a cutting-edge supercar, gifted to himself and secured in the basement garage. The newly acquired car is yet to be installed with tracking features, so this is your chance to strike.

As you infiltrate the party, you’ll need to bypass advanced laser grids, dodge high-tech security cameras, and outmaneuver patrolling guards, all while staying out of sight from the festive guests. The map is packed with features to test your ingenuity, including hackable security systems, and multiple entry points, allowing you to tailor your approach to the heist.

Can you outsmart the millionaire, outwit his security, and make your daring getaway? The stakes are high, and the spotlight is on you.

  • Security systems including guards, cameras, and state-of-the-art vault protection

From One-armed robber

Black Diamond Casino - try to win it big on the slots, or try to win bigger by robbing the place!

This casino is filled to the brim with money, in the form of chips, cash and bonds! This also means that the casino is strictly secured with guards and cameras around every corner, and state of the art security systems.

If you manage to sneak around security and make your way into the vault, the high-tech security system will reveal itself. Inside the vault is 2 arrays of lasers which can be deactivated, but only for 30 seconds at a time, so you will have to hurry in order to not be trapped inside the vault!

Snoop around a little further and you will find a guarded basement locked with a biometric hand scanner, this scummy casino is the weekly gathering point for mobsters, who gather and play poker while they do their dealings. This is the perfect time to interrupt as the basement will be filled with valuables. But only the hand of a mobster can unlock the door!

To acquire these skills you will have to research them, you pay cash to start the research, the skill research will then progress when you play the game, once the research is finished, the skill will be unlocked and automatically equipped.

Sounds and Music!

Added 5
  • Sound effects for objects and items
  • Ambient and environment sounds
  • Menu music
  • Music that plays when the alarm is tripped in-game
  • Additional achievements

From One-armed robber

An aspect of the game that has been lacking has been the sounds. A lot of items have had missing sound effects, and ambient sounds and music were non-existent. But not anymore!

A lot of you have also been asking for this update for a long time, and we’ve spent a lot of time finding and recording sounds. This update adds sounds to a lot of new things, this includes sound fx for objects, but also ambient and environment sounds.

As well as a bunch of sound effects, this update also adds music! This includes menu music, and music for when the alarm is tripped ingame. Some of this music is temporary, while we work on creating our own original music for the game.

We’ve also added a few more achievements

Rodman research facility update

Added 1
  • Added a warehouse to the back of the building as another place to enter through
Changed 3
  • Slightly changed the layout of the map to make it easier and provide more ways to complete the heist

From One-armed robber

We’ve slightly changed the layout of the map to make it a little easier and to give you some more ways to complete the heist. A warehouse has been added to the back of the building, giving you another place to enter through. The layout of the building is still the same on the inside except for the new entrance.

The value of the beakers has also been increased to match the difficulty and length of the map.

The map has also been upgraded visually in some places by adding some more details, and changing the overall look of some areas.

Changes to the appearance shop

Added 1
  • Civilian casualty penalty deducts from your total take at the end of the game if you kill civilians
Changed 2
  • Appearance shop now offers 2 weekly items instead of rotating featured items
  • Almost all previous appearance shop items are now available in the shop

From One-armed robber

Appearance shop We have decided to change the way the appearance shop works in the game. From now on, there will only be 2 weekly items, the “featured items” section will become “all items”, and almost all previous items will be available in the shop.

We’ve decided to make this change because we want to spend our time on making new gameplay content and maps for the game. We were spending too much of our time making skins, and not enough time on content. We have a lot of plans for the game, and since we’re a small team, it was hard to allocate enough time towards it. We hope you can understand our decision. Expect to see more content very soon!

Civilian casualty penalty We’ve also added a “civilian casualty penalty” meaning if you kill civilians you will be punished by having some of your total take taken from you at the end of the game. This makes it more attractive to tie up civilians instead of shooting them.

Lundenburg Liquors

This liquor shop is like most others, however they also have one of the most expensive wine collections in the country. You can find this collection in their wine cellar. Since their collection is so expensive, they also made an effort to secure the place, by purchasing top of the line security systems such as lasers, and security tags on their most expensive wine bottles.

The wine cellar is divided into six cells, each with a shelf containing various wines. Behind the bars of each cell is an array of lasers, if anything touches these lasers, the alarm will go off, luckily you can disable the lasers, using the box in the far end of the room.

Once inside the cells, you will notice, that some of the bottles have a white cap on them, this is a security tag. At the entrance of the wine cellar is a security tag detector, which will set off the alarm if any of the bottles leave the room, therefore you will have to find a way to disable the security tag detector before getting the bottles out.

New maps and special police types!

Added 7
  • Add Liberty Hawk bank map, a small bank in the city suitable for inexperienced robbers with no advanced security systems but limited cash
  • Add Rodman Research Facility map, a remote research facility where you collect beakers of chemical compounds and process them through a centrifuge to create high-value chemical weapons
  • Add Powerbox defuser special police unit that moves faster than regular police and focuses solely on defusing powerboxes
  • Add Juggernaut special police unit equipped with a heavy machine gun and heavy armor suit, weak to shots through the face visor
  • Add Interceptor special police unit that places barbed wire traps in doorways to slow down the player
  • Add Shield special police unit that carries a bulletproof shield and pistol, vulnerable to shots at the glass or visible limbs
  • Add Blinding shield special police unit similar to the Shield unit but equipped with bright lights that blind players in front of it

From One-armed robber

The first content update for One-armed robber is here, with 2 new maps, and special police units, there is a lot to get excited about!

Maps

Liberty Hawk bank

A small bank in the city, perfect for the inexperienced robber. This bank doesn’t have any advanced security systems, but also doesn’t contain that much cash. This bank is perfect for a novice robber learning the ropes, or an experienced robber wanting an easy challenge.

Rodman Research Facility

This remote research facility is developing secret chemical weapons that are worth a lot of money in the right hands! In each room is a beaker with the chemical compound, put this through the centrifuge in the laboratory to transform it into a high-value chemical weapon, which is worth a lot.

Special police units

Powerbox defuser

Now with its very own special unit, the powerbox defuser does what regular police previously did; defuse powerboxes. However the special unit moves a lot faster, and is unarmed, making his only target the powerboxes, so watch out for him! turning your back to a powerbox for just a few seconds, and he might have defused it.

Juggernaut

The Juggernaut unit is equipped with a heavy machine gun, and his heavy armored suit makes him incredibly difficult to get rid of, but also very slow. Shooting him through the face visor is probably your best option.

Interceptor

The Interceptor is a sneaky guy, running around placing barbed wire traps in doorways and other places. These traps will slow you down, making you an easy target for the police, shoot the barbed wire to get rid of it, and shoot the interceptor to stop him from placing barbed wire.

Shield

This unit carries a completely bulletproof shield in one hand, and wields a pistol in the other. The shield makes him very difficult to kill, however the shield has a weakness; the glass. Breaking the glass gives you direct visibility to his head, making it easy to take him out. Alternatively you can try to shoot at any limbs visible around the shield.

Blinding shield

very similar to the regular shield unit, except this guy has a shield equipped with extremely bright lights that will blind anyone in front of them. Try to shoot this guy before he has a chance to activate them!
