About this game
Survive relentless waves of infected in this top-down survival shooter. Face increasingly difficult hordes in confined zones, earn currency, and upgrade your arsenal to stay alive as long as possible.
Core Gameplay Inspired by classic wave-based zombie survival mechanics, your primary objective is to hold your ground. Eliminate incoming threats to earn money, which can be used to purchase stronger weapons and better equipment between waves. Each successive wave introduces higher difficulty parameters and more aggressive enemy behavior.
Multiplayer and Progression Hold the line alone in single-player or team up with friends in online co-op. Survival is only part of the equation; the ultimate goal is to accumulate the highest possible score. Compete against a global player base and climb the ranks on the worldwide leaderboards.
Key Features:
Top-Down Survival Action: Fast-paced, tactical combat against endless zombie waves.
In-Game Economy: Earn cash from eliminations to unlock and purchase a diverse arsenal of weapons.
Escalating Difficulty: Enemy count and threat levels increase dynamically with each cleared wave.
Game Modes: Fully playable in both solo and online co-op multiplayer.
Global Leaderboards: Track your high scores and compete for the top position against players worldwide.
