Farewell to Arms will add in two new playable characters, a secret level that was made less secret by this press release announcing it just now, an "arsenal" of new weapons, and more. According to this release, this will be the "last free update" for Enter the Gungeon. That can either mean there will be some paid content in the future or, and this one is more likely, the team feels as though they are ready to fully move on to their next project.
Farewell to Arms is the third big content drop for the game. The first two were Supply Drop and Advanced Gungeons & Dragons. These two releases were also free. So far, Enter the Gungeon has sold roughly 2.5 million copies across PC, PlayStation 4, Xbox One, and the Nintendo Switch.
The update offers a first for Gungeon expansions; two new playable Gungeoneers in The Paradox and The Gunslinger. Battle-tested Gungeoneers will welcome the arrival of dozens of new guns and items, a new secret floor with a devious boss, and the addition of the community-inspired Rainbow Mode. Additional features, tweaks and fixes are also included, keeping in line with the goal of making the player feel “more powerful, more often†reinforced in the previous update.
