OVERZERO: Before Dawn – Prologue

By OverZero games

A free browser survival spin-off with automatic weapons, cybernetic virus hordes, evasive movement and evolving upgrades.

OVERZERO: Before Dawn – Prologue is a browser survival game set on the first night of a virus flood in the network. Dark violet pixel-art arenas fill with enemies, neon projectiles and red danger zones. Weapons fire automatically, leaving the player to find gaps, maintain distance and steer through the horde.

Position carefully and build your weapons

The official controls use WASD or the arrow keys for movement and Space for LINK BURST. Upgrades build a loadout during each run. According to the developer, a level-eight weapon evolves when paired with its required passive, while enemy attacks show red warning cues before they land.

A short chapter before dawn

OverZero games lists three stages and three bosses—HYDRA CORE, SPOOL STINGER and THE OVERRUN—with an estimated 30–45 minutes to reach the ending. There are six characters: three are available initially, and clearing stages unlocks the others. Each has her own weapon, perk and LINK BURST.

The game is free to play in a browser without registration, with keyboard, mouse, gamepad and landscape touch controls. Saves are stored in the browser on each device. English and Thai support are both still in development.

This is a spin-off set before OVERZERO: The First Dawn, not a completed release of the main project. An expanded OVERZERO: Before Dawn with more content and ENDLESS remains a future plan.
