Hammer95 Studios has introduced an exciting update for its acclaimed retro FPS, Mullet MadJack. Released on December 19, the new Boss Rush Mode brings an intense challenge for players to face a series of bosses in a race against the clock. The free update also includes an explosive surprise: a crossover with ULTRAKILL, the frenetic retro-action FPS.

After receiving phenomenal acclaim over the past six months—with a Metascore of 88, over 6,000 user reviews on Steam (97% positive), and 560,000 wishlist additions—Hammer95 Studios, in partnership with publisher Epopeia Games, continues to deliver innovative and challenging content for fans of the genre.

The Boss Rush Mode not only tests players’ reflexes and strategies but also promotes global competition through leaderboards that reward the fastest times. With each boss defeated, the race against the clock intensifies, providing an experience that challenges both skill and endurance.

The collaboration with ULTRAKILL takes the challenge to a new level. As the final showdown in Boss Rush Mode, one of the most iconic villains from the ultraviolent universe of ULTRAKILL appears to push players to their limits. This unexpected fusion of worlds promises memorable battles and an extra dose of adrenaline.

With this update, Mullet MadJack reinforces its position as one of the most exciting indie FPS games of the moment, delivering fresh experiences and keeping players immersed in its frenetic retro action.
