Megabonk’s Unhinged New Replacement Is Officially Free On Steam Now

Megabonk was one of the most surprising and unexpected hits of 2025, though despite its meteoric popularity, the game’s developer has more or less abandoned it after the last Halloween update that introduced a new map, character, and boss. That said, Megabonk‘s simple premise, bizarre yet addictive gameplay, and infinite replayability inspired an avalanche of similarly styled indie games.

While Megabonk-likes have taken the bullet-heaven premise to the extremes and experimented with all sorts of different genres, mechanics, etc., there’s one game in particular that fans of vedinad’s hit will absolutely not want to skip. Better yet, the game is entirely free to try on Steam starting today, November 12, 2026, thanks to a newly launched demo.

If Megabonk wasn’t already wild enough for you, there’s a new Steam game that takes the same basic premise and cranks things up several notches. Developed by Aquila Games, Together, Against Mork combines the ridiculous combat of a bullet-heaven roguelike with tower-defense mechanics, giving players even more ways to deal with overwhelming hordes of enemies. Best of all, a free demo for Together, Against Mork is officially available on Steam starting November 12, letting players experience the action without spending a dime.

At its core, Together, Against Mork shares plenty of DNA with Megabonk, with players fighting off enormous waves of enemies, stacking upgrades, and experimenting with increasingly powerful builds. However, its biggest selling point is the addition of an entirely separate tower-defense system that introduces a twist to the mix and an entirely new strategic element to the carnage.

According to the game’s official Steam page, there are three distinct modes to choose from:

• Tower-Defense Mode: Players defend themselves and a central Crystal from incoming waves of enemies. Between waves, they can spend Build Coins to construct walls, deploy defensive towers, and summon friendly units, including Minions and Fat Guardians, to help hold back the hordes.
• Classic Mode: A more traditional Megabonk-style experience that removes the defensive structures and Crystal entirely, allowing players to roam freely, stack upgrades, and survive against increasingly overwhelming enemies until the timer expires.
• Endless Mode: A seemingly never-ending survival challenge featuring progressively harder stages, changing maps, and new enemy waves, pushing players to see just how far their increasingly ridiculous builds can take them.

Beyond these modes, Aquila Games is promising an impressive amount of content for the full release, including seven unique maps, more than 30 enemy types, and over 20 playable characters. Challenges, rewards, and permanent upgrades should also give players plenty of reasons to return for another run. The developers even describe the experience as “insanely chaotic,” promising game-breaking synergies and last-second Hail Mary victories.

While the full version of Together, Against Mork has yet to receive a confirmed release date, its free Steam demo gives Megabonk fans an opportunity to try a promising new alternative, particularly for anyone who enjoys a little strategy mixed in with their roguelike mayhem.
