DISCORD
The zombie apocalypse is here—fight to survive and break out of the infected zone!
A sudden viral outbreak has turned the city into a living hell. Face endless hordes of zombies and seek survival amidst despair in this top-down, solo or co-op action survival game! Combining roguelike randomization with fast-paced combat, the game supports hardcore solo challenges or 4-player co-op—surviving the apocalypse is never lonely.
■ Endless Zombie Hordes ■
Zombies come in waves, each more ferocious than the last!
Dynamic Threat System: Hide by day, rage by night! Nighttime sees more zombies with greater detection.
Horde Warning Mechanism: Predict large-scale attacks through ground tremors and distant screams.
Ultimate Goal: Break through the encirclement and reach the safe zone before total collapse!
■ Deep Build System ■
30+ unique talents that completely change the gameplay.
10+ weapon types, from fire axes to grenade launchers, each with distinct feel.
10 ultimate skills: call airstrikes, throw explosive grenades, or even temporarily control the undead.
Free playstyle combinations: melee berserker, trap master, drone summoner… your imagination is the limit.
■ 4-Player Co-op Mayhem ■
Lone wolves may die, but teammates can be even more dangerous!
Supports 4-player co-op sharing survival resources… or stealing the last medkit.
“Friendly Fire Moments”: AoE skills hit indiscriminately—watch out for your team!
Co-op Mechanics: Character skills can interact (e.g., Drunk’s Molotov + Engineer’s Drone = fiery bombardment).
■ 10 Unique Characters ■
Each character offers a completely new gameplay experience:
Bombproof Officer: Shield forward, but 20% slower movement.
Drone Engineer: Aerial reconnaissance, but melee damage halved.
Pyro Drunk: Throws Molotovs, drunken state triggers random crits or self-damage.
Demolition Expert: Grenades open the path, but watch out—don’t blow yourself up!
…plus 6 hidden characters to unlock.
■ 8 Treacherous Maps ■
Each map presents unique survival challenges with different resources and dangers:
Old Town: Narrow alleys easy to defend, but abandoned vehicles can block paths.
Hospital: Rich in medical supplies, yet the morgue may erupt with zombies.
School: Open playground, classrooms form deadly mazes.
Quarantine Zone: Military fire traps; misuse and get burned.
Shopping Mall: Christmas lights can blind zombies, glass skywalks may collapse.
Downtown: Tall buildings for sniping, but zombies swarm from underground garages.
Dockyard: Container mazes allow flanking, dampness reduces fire effectiveness.
Sewers: Toxic areas require gas masks but contain rare upgrade parts.
(More death arenas under development…)
■ Intelligent Hordes & Deadly Bosses ■
These aren’t mindless zombies—they learn, evolve, and hunt:
Special Infected:
Butcher: Can slice players into pieces.
Banshee: Attacks rapidly when disturbed.
Pustule: Explodes on death, damaging nearby players.
Acid Spitter: Shoots corrosive slime at range.
Burrowing Sandworm: Ambushes from underground causing knockdown.
Blood Leech Swarm: Attaches to ceilings/water, heals itself by draining life.
Mutant Rat Pack: Carries random debuffs (slow, blurred vision, bleeding).
Splitter: Splits into two smaller units when fatally injured.
Invisible Hunter: Completely transparent while moving, reveals only on attack.
(More monsters added continuously…)
Dynamic Bosses:
Military Experiment: Uses leftover tactical gear, targets healers first.
Mutant Giant Baby: Devours corpses to heal, takes triple damage from fire.
Zombie Dog Pack: Double movement speed, reduced headshot damage.
“Remember: when you hear laughter, it’s already too late…”
“Since the apocalypse is here, enjoy the last thrilling moments to the fullest!”
