| Sounds and Music! | 2024-02-22 | 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 musi |
| Achievements | 2024-02-21 | You will now be able to unlock achievements by completing various challenges and tasks in-game. There are more than 30 achievements to unlock, ranging from Picking locks to killing police! Although many of you might technically already have reached one or more achievements during your time playing the game previously, that unfortunately won’t count towards progress for the achievements. And all achievement progress will only start counting from this update forward! |
| Rodman research facility update | 2024-02-02 | 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. |
| Map Sale | 2024-01-31 | From now and until Feb. 6. all maps are 25% off! |
| Changes to the appearance shop | 2024-01-25 | 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 |
| Lundenburg Liquors | 2024-01-19 | 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. |
