The melee combat has been revamped with the addition of a blocking mechanism; attack motions are now dictated by the player character's direction of movement. Tripwire are also introducing a new perk progression system, that allows for more customization. To alleviate the perk levelling grind from the first game, the number of levels has been increased drastically to allow players to level up more regularly. Each perk now has configurable skills along with passive bonuses. Tripwire are planning to implement support for Steam Workshop and release a software development kit to allow for extensive modding.

In November 2015, Tripwire added a in-game store to allow players to purchase cosmetic items for their characters via microtransactions that otherwise had no effect on gameplay. Many players expressed concern with this addition, as the game at this point had not left Early Access, and that a similar situation had recently occurred with Payday 2 by Overkill Software where the addition of micropayment-based content was met with harsh feedback. Tripwire replied to its player base that the decision to add this feature now was to get feedback to make the transition from early access to a final release seamless, and that while it also added new content such as new weapons, these are treated as shared content that all players on the same server would enjoy. In March 2016, Tripwire updated the game on PCs to include support for Steam Workshop support, allowing users to provide their own maps, weapons, character models, and other modifications. The game was released on 18 November 2016 for Windows, and PlayStation 4.
