This update adds a new holiday-themed version of the "New York" map, with snow-covered streets, new ambient lighting, and three secret holiday-related tasks that players can complete. Players who manage to complete all three of them are rewarded with a new achievement, and a new "Pine Tree" weapon pattern!
The "Swarm" cop class also received a full rework: The idea was to create a gadget-focused cop that could pro-actively set up defenses against the robbers, but the drone-based approach forced robbers into attacking him early instead of focusing on a stealthy approach, while his remote-controlled drones allowed him to be at multiple places at once. The old Swarm is now officially removed from the game, but can still be played by selecting the new "Removed" characters pack.
The new, reworked Swarm still focuses on gadgets, but can no longer remotely control them, and doesn't spawn with them anymore, instead, he places them into the world like most other classes. He can place an unlimited amount of gadgets, only being limited by his "Idea Sparks" resource which can be increased by reading Secret Files. His gadgets include a new "GrumpyBOT" motion detector, which automatically fires on characters that cross its laser detector, dealing around 20 damage. His Spark-O-Tron is a small robot that drives around aimlessly, bouncing off walls and stunning any characters that come too close, while his modified "Sweep-O" cleaning robot drives to nearby fires to automatically extinguish them.
The class selection screen also received some changes, robbers can now select their spawn by pressing directly on it, instead of having to cycle through all available spawns. Players can now also cycle through the different floors of the bank to make planning the perfect heist easier. The level editor also got upgraded, map creators will now find a new "Create Folder" button, which will create a new folder that includes all selected items, making the object list more concise and allowing players to convert the new folder into a "Prefab". Created Prefabs can be used like any other existing object in the level editor, allowing creators to quickly place them inside their maps. Prefabs can also be uploaded and downloaded through the Steam Workshop, which makes sharing your favorite custom objects, logic setups, and setpieces. A new "Multi-Purpose Zone" has also been added to the level editor, which allows map creators to quickly apply one or more of the following effects on players inside the zone:
