A 3D bullet-heaven roguelike that makes two dimensions feel like a downgrade, even with only two biomes doing all the work.
Official art · via Steam
Megabonk takes the Vampire Survivors formula and gives it a third dimension: full verticality, sliding, jumping, and speed-boost chaining instead of a flat arena and a joystick. Solo developer Vedinad built the shift around movement tech that rewards piloting your character while the auto-combat handles the shooting, and it lands well enough that going back to a 2D survivors-like feels like a step down.
Twenty unlockable characters carry distinct kits, a damaging aura for one, wall-climbing and boomerang bananas for another, and a pool of 70-plus items stacks flat and percentage buffs into builds that diverge run to run. Teleporter-triggered boss fights borrow Risk of Rain 2's structure instead of a pure survival timer, and 240-plus quests plus a Silver currency for unlocks give a three-level game more reasons to return than its size suggests.
Three levels means two biomes, and that's the game's real ceiling. Reviewers flagged the repetition directly: the same two backdrops start to wear thin well before the unlock list runs dry. Some late bosses lean on cheap-feeling difficulty instead of a fair check, including a surprise instant kill and a health-bloated wall that can turn a thirty-minute run into a dead end. Challenge modifiers mostly pad enemy health rather than change how a stage plays, and the meme-heavy humor, jokes with names like "Cooked" and "Chadbark," split reviewers between charmed and annoyed. A balance patch that made one character trivialize leaderboard runs drew real, documented backlash on the game's own forums before a follow-up patch walked it back.
Roughly 94 percent of more than 100,000 Steam reviews rate it Very Positive, and Metacritic's 88 comes from a small but consistently strong set of critics (Destructoid 90, Gamereactor UK 90, PC Gamer 88). The developer withdrew the game from its own Game Awards nomination in November 2025, saying publicly that past unreleased work under other names disqualified it from a "debut" category, a rare bit of self-imposed integrity for an indie hit riding this much momentum.
Buy it. The movement and build variety carry a three-level game further than it has any right to go, even if the map count catches up to you eventually.
