Why players say this

Steam review verdict

Praised for its music, art, and short-term fun, but suffers from UI text issues, broken multiplayer, and performance lag.

What players like

Promising but needs fixes: Multiple reviews acknowledge potential and a solid foundation, but they emphasize that improvements are needed for the game to reach its full potential.

Megabonk co-op potential: The core concept of Megabonk in a cooperative mode is highlighted as a fantastic and interesting idea, showing strong thematic appeal.

Music design praised: The music and overall aesthetic design receive consistent positive mention, with specific praise for the soundtrack and its initial appeal.

Enjoyable short-term fun: The game is described as fun for a limited duration, particularly a couple of hours, suggesting it has initial engagement but may lack lasting depth.

Multiplayer demand arises: There is a desire for a multiplayer Megabonk mode, though it is not currently present in the game, pointing to a requested feature.

Common complaints

UI text issues: Multiple clusters report buttons and text in Russian, missing descriptions for items/character unlocks, and missing tooltips. This affects usability.

Multiplayer/co-op broken: Clusters 8, 22, 77, 95, 115, 116, 117, 125 report that co-op and multiplayer have severe issues: no shared resources, no progression, lobby kicks, random disconnects, and no playtesting.

Performance and lag: Clusters 9, 27, 45, 46, 82, 122 report FPS drops, lag in four-player mode, poor optimization, and low frame rate even on high-end hardware (RTX 3060).

Enemy/boss problems: Clusters 56, 60, 63, 67, 76, 131 highlight that enemies lack variety, ignore base distance, attack instantly, and bosses have no pattern beyond bullet-sponge health.

Chest and loot bugs: Clusters 10, 19, 70, 86, 94 describe chests as buggy (invisible, already open, random costs, no interaction button) and requiring too many fragments for limited rewards.

Gameplay and performance

Multiplayer is flawed: Co-op has no shared resources, each player gets own exp and crystals, and there is no coordination. Lobby setup is weird, and only 2 characters are unlocked for 4 players.

Unclear progression systems: Multiple unlock systems like tokens, chests, and fragments are poorly explained, with no hover info or unlock conditions. The grind is heavy with each item needing 15+ fragments.

Lack of co-op mechanics: Multiplayer mode has no shared resources or experience, making it feel like two single-player games. This leads to one player watching if there is a level difference.

Chest system is confusing: Chests have no logic, limited content, and give fragments from a mixed pool of 3-4 different items. Each item needs 15+ fragments to combine, making it a grind with no clear reward.

Enemy design is poor: Mobs always target the player, have no special skills or attack patterns, and run into you with instant hits. No cooldown allows continuous attacks, making combat unfair.

General performance problems: Multiple clusters describe overall poor performance, including lag, low FPS, and stuttering, with no single cause identified.

Poor optimization criticized: Feedback labels the game's optimization as 'garbage' and 'not released,' suggesting deep frustration with the current state of performance.

Lag in 4-player co-op: Players experience significant frame rate drops and lag specifically when four players are together, indicating a multiplayer performance bottleneck.

High GPU temperatures reported: Nvidia RTX 20, 40, and 70 series GPUs are running hot, with reports from RTX 2060, 4060, and 4070Ti users, suggesting thermal issues across multiple generations.

Low FPS on mid-range GPU: An RTX 3060 system is reported to run at only 30 frames per second, which is below expected performance for this capable graphics card.

Recommendations

General negative recommendation: Players widely advise against purchasing or playing the game in its current state, urging others to wait for updates or patches before investing time or money.

Mixed quality despite co-op: One review notes the game is mediocre and even cooperative play does not improve the experience, suggesting core gameplay issues beyond multiplayer.

Buying context

Session length: 3.0h.

Endgame: 200.0h.

The game offers fun with friends in the Megabonk style, but early access bugs, controller issues, and poor co-op design (no shared progression, lobby reconnecting) create significant friction, making co-op mode currently not enjoyable for many.

Friction: controller not working on launch; high-speed early mobs causing instant death; no shared experience or progression in co-op; lobby system requiring reconnection after every match; numerous bugs and audio issues.

Unlock drivers: learning enemy patterns and upgrades; using keyboard/mouse instead of controller; waiting for hotfixes and patches; accepting early access roughness.

Player profiles

Solo Grinder: Plays alone, grinds meta-upgrades, tolerates repetitive runs for dopamine hits. Motivation: Addictive core gameplay loop and progression system. Stance: buy.

Frustrated Co-op Seeker: Attempts coop, suffers through lobby issues and unfair instant deaths, puts the game down until fixes. Motivation: Playing a survivor-like game cooperatively with friends. Stance: no buy.

Cautious Waiter: Wishlists, reads patch notes, plays demo, then waits for major fixes before committing. Motivation: Seeing the full vision of a polished, finished product. Stance: deep sale.

Platform notes

The game shows performance issues in the 8-11GB VRAM range, based on a single review that cites problems possibly due to the Unity engine.

Windows 8-11GB VRAM: negative. A single review with 12GB VRAM on Windows 11 reports performance problems, suggesting instability in this hardware range.
