GAME OVERVIEW

Cockroach Killer 5000 is an intense, darkly comedic exterminator simulator where you face endless waves of photo-realistic cockroaches in a desperate battle for cleanliness. Armed with an arsenal of household weapons ranging from a simple hammer to explosive bug bombs and flammable gasoline, you must survive increasingly difficult waves where thousands of roaches will test your reflexes, strategy, and nerve.

This isn't your typical pest control job—it's an all-out war against nature's most resilient survivors.

CORE GAMEPLAY

Objective: Exterminate every cockroach in each wave. Survive as long as possible. Rack up the highest score.

Endless Wave System:

Start with 30 roaches in Wave 1

Each subsequent wave spawns more roaches (~18 additional per wave)

Roaches become faster and more numerous as you progress

Waves continue until you're overwhelmed or achieve cockroach genocide

Potential to face 200+ roaches simultaneously in later waves

Mouse-Only Controls:

Point & Click combat system

Select weapons from the right-side panel

Click anywhere on the floor to attack

Hold for continuous-fire weapons (Raid spray)

Strategic cursor placement is key to survival

ARSENAL: 5 DEVASTATING WEAPONS

🔨 HAMMER (Unlimited)

Your starter weapon and fallback option. Instant kill on direct hit with a tiny impact radius. Requires precision but never runs out. Perfect for stragglers and conserving ammo.

💨 RAID SPRAY (100 charges per wave)

Medium-range pesticide cone. Spray roaches with a continuous stream of toxic mist. Damages multiple targets in the area. Roaches panic and scatter when hit. Refills +40 charges each new wave.

💣 BUG BOMB (3 per wave)

Throw and retreat! Fuses for 1.5 seconds before detonating in a massive area-of-effect explosion. Kills everything in a huge radius. Also ignites nearby gasoline pools for combo devastation. Strategic placement is critical. Refills +2 per wave.

🧪 BLEACH (15 pours per wave)

Pour toxic puddles that persist for ~15 seconds. Any roach that walks through bleach takes continuous damage until death. Perfect for choke-points and area denial. Refills +8 per wave.

⛽ GASOLINE + FIRE (5 cans per wave)

The ultimate combo weapon:

Pour gasoline puddles on the floor (lasts ~40 seconds)

Click an existing puddle to IGNITE it

Fire spreads to all connected/overlapping puddles

Create chain reactions for massive kill combos

Roaches touching fire panic, speed up, and burn to death

Bug bombs also ignite gas pools for spectacular combos

Refills +3 cans per wave.

ENEMY BEHAVIOR: INTELLIGENT ROACHES

These aren't mindless sprites—they're sophisticated survivors:

Emergent Movement: Roaches crawl from random screen edges with unique pathfinding

Panic System: Explosions, fire, and near-misses cause roaches to flee erratically

Speed Scaling: Each wave brings faster roaches (+4 speed per wave)

Fire Reaction: Roaches on fire move 2.2x faster in blind panic before burning to death
