Why players say this

Steam review verdict

Addictive zombie-killing fun with varied perks, but frequent fatal crashes wipe progress and content feels thin.

What players like

Addictive and fun gameplay: Players consistently describe the game as addictive, fun, and entertaining, with gameplay that doesn't disappoint. This sentiment is echoed across multiple clusters, indicating a strong positive reception.

Fun zombie-killing action: Players enjoy killing waves of zombies and surviving as long as possible, with hordes flooding the streets. The top-down twin-stick shooter style adds to the chaotic fun.

Variety of perks and power-ups: The game offers a big variation of fun power-ups, temporary and permanent perks, and a skill point system with random choices. These features add depth and replayability.

Great weapon variety: The game offers a wide range of weapons with different fire rates, reload times, and properties, including shotguns, flare guns, and plasma guns. This variety keeps gameplay fresh and engaging.

Twitch integration enhances experience: Twitch integration allows viewers to influence the game, adding unpredictability and replay value. Multiplayer modes with this feature are rated as excellent.

Common complaints

Frequent fatal crashes: The game crashes regularly, often after 40 minutes to an hour of play, with fatal errors that make it unplayable. This is the most common and severe issue reported.

Progress lost on crash: Crashes erase all progress from the session, including weapon unlocks, because the game does not save progress. This compounds the frustration of frequent crashes.

Lack of content: Players describe the game as empty, soulless, and lacking in content, which contributes to a sense of boredom and repetition.

Repetitive gameplay: The gameplay is monotonous and not varied, leading to boredom, especially when playing alone. This is a common complaint that reduces long-term engagement.

Poor graphics quality: The graphics are described as chunky and of low quality, which detracts from the overall experience.

Gameplay and performance

Co-op mode available: The game offers a local co-op mode for two players, with some modes sharing a health bar. This is a notable feature for players seeking multiplayer experiences.

Vault defense mode: A dedicated defense mode involves protecting a vault or bunker entrance using turrets. This mode is distinct from survival and adds strategic variety.

Survival mode with waves: Players kill waves of zombies and try to survive as long as possible, with leveling up by killing enemies. This is a core gameplay loop.

Twin-stick shooter mechanics: The game is described as a top-down twin-stick shooter, indicating precise aiming and movement controls. This is a key gameplay element.

Twitch integration for viewers: The game has Twitch integration allowing viewers to influence gameplay through voting or chat commands. This enhances streaming interactivity.

Poor optimization and bugs: Players describe the game as poorly optimized and buggy, with general performance issues and minor bugs affecting the experience. This contributes to a sense of low polish.

No graphics settings: The game lacks graphical settings and resolution options, preventing players from adjusting quality to improve performance. This is a notable omission for a PC title.

Performance issues with lag: Players experience lag and stuttering, especially when many zombies are present, and on low-end PCs. This can make the game feel unresponsive, like high ping.

Hardware demanding and overheating: The game is demanding on hardware, leading to GPU overheating and system shutdowns in some cases. This is a serious concern for players with less robust systems.

Handheld performance solid: One player reports that performance is solid on handheld devices like Steam Deck and ROG Ally, suggesting the game may run well on certain hardware configurations.

Recommendations

Buy on sale: Several reviewers recommend purchasing the game only when it is on sale, indicating that the value proposition improves significantly with a discount. This is a common sentiment across multiple clusters.

Do not recommend: A number of reviewers explicitly state they do not recommend the game, often without specific reasons or due to technical issues. This negative sentiment is spread across several clusters.

Not worth full price: Multiple reviewers advise against paying full price, suggesting the game is only worth it on sale or at a discount. Some explicitly recommend waiting for an 80-90% off sale or buying it for a few euros.

Recommended for genre fans: Reviewers recommend the game to fans of top-down zombie-killing games, arcade shooters, and survival games. This suggests the game appeals to a specific niche audience.

Technical issues and crashes: Reviewers report fatal errors, crashes, and the game not working properly, which prevents them from recommending it. Some mention the game crashes just when it gets good.

Buying context

Community fair range: $2.99 - $4.99.

Session length: 60.0h.

Endgame: 2.0h.

The game starts with a steep learning curve, especially around bosses, but becomes enjoyable once players master the mechanics, particularly in co-op or multiplayer modes. Some players find fun immediately, while others never click, but the dominant reported progression is early friction leading to later enjoyment.

Friction: steep learning curve; difficult boss encounters; singleplayer mode feels like a tutorial; repetitive sounds; buggy and unpolished mechanics.

Unlock drivers: getting the hang of the game mechanics; mastering boss encounters; playing co-op with friends; engaging in multiplayer modes.

Player profiles

Casual Co-op Buddy: Plays co-op with a friend, casually, without grinding or achievement hunting. Motivation: Social fun and casual entertainment with friends. Stance: buy.

Frustrated Completionist: Grinds specific tasks and achievements, often solo or in co-op, checks achievement progress. Motivation: Unlocking all achievements, but blocked by bugs and crashes. Stance: no buy.

Bargain Hunter: Waits for sales, plays casually, not deeply invested. Motivation: Getting good value for money, avoiding overpaying for a game with limited replayability. Stance: deep sale.

Platform notes

Steam Deck: The game suffers from frequent crashes, which is a major issue. While it can run on Steam Deck with Proton Experimental and performance is solid, the stability problems make it a broken experience.

Linux and Proton: The game appears to work on Linux with Proton Experimental, as confirmed by a user on Kubuntu, and performance is solid on Steam Deck. However, one user reports graphical glitches on X11/Wayland, which may be a minor issue or resolved by using Proton Experimental. Overall, the game requires a Proton version tweak but is playable.

Other review notes

Compared to other shooters: Reviewers frequently compare the game to titles like Alien Shooter, Zombie Shooter, Crimsonland, and Robotron 2084, often recommending those alternatives. This suggests the game is seen as a derivative or inferior version.

Low price purchase common: Multiple reviewers mention buying the game at a low price or during a sale, indicating it is often acquired cheaply. This suggests the game is seen as a budget title.

Developer support ended: Several clusters indicate that the developer no longer supports the game, with no updates or bug fixes. This is a significant concern for players expecting ongoing maintenance.

Achievements and cards: The game has Steam Trading Cards and Achievements, and some players bought it specifically for cards. Achievements can be unlocked quickly, which may appeal to collectors.

Platform availability: The game is available on multiple platforms including Xbox One, PS3, PS4, PS Vita, Switch, and PC, and works on Steam Deck and ROG Ally. This broad availability is a positive aspect.
