SIGMA EDITION - initializing the upgraded defense runtime...
Higher levels spawn enemies faster and make armored, runner, and tank toilets scale harder. Choose wisely.
Nothing moves while paused.
Flip these mid-run. They reset when you reload the page.
Recruit Cameramen, Speakermen, and Legendary Titans! Hired units deploy directly into the sewer battlefield to eliminate toilets, hold back breaches, and provide heavy fire support.
Spend skill points down a branch; later nodes stay locked until you buy the one above them. The arsenal above auto-fires once owned — mix direct fire with support gear (burn, freeze, stun, drones, lightning) to survive longer.
Your local hardware could not handle the raw unoptimized asset scaling.
The sewer drainage facility is under assault by rogue toilet invaders. Hold the defensive perimeter at all costs!
The yellow hazard line across the sewer floor is the reinforced breach threshold. Toilets that cross this line drain Lives. Prevent any enemy from passing!
Click or tap directly on approaching toilets to smack them with plungers. Rapid clicks build Combo Multipliers (up to 4.0x score & faster ability recharge).
Defeat colossal Bosses every 5 waves to trigger the Sigma Relic Protocol: draft 1 of 3 permanent physical relics to create game-changing run synergies.
Place interactive ground traps directly on the sewer floor using Sigma Energy:
Launches toilets backward with bowling-pin cascade physics! Flying toilets crash into trailing enemies behind them, delivering heavy impact stun.
Lingering boiling acid pool that melts enemy armored plates and reduces movement traction so your defenders can easily pick them apart.
Heavy volatile drum placed in the arena. Shoot, click, or detonate it when toilets swarm nearby for a massive 185px shockwave explosion!
Recruit autonomous units that physically run and brawl across the sewer floor in the Barracks [H]:
Fast frontline sprinters wielding dual plungers. They chase down toilets and deliver rapid physical melee beatdowns.
Colossal armored titan! Slams a spinning diamond drill into the sewer floor to generate devastating seismic fissures across enemy lines.
Four-legged cybernetic canine. Sprints at high speed, leaps onto toilets, and locks them in place with high-voltage jaw grapples.
Low-altitude airborne commando. Strafes across the battlefield spraying rapid twin-bullet volleys into the swarm below.
Keyboard shortcuts & primary abilities:
Fires a full-arena EMP pulse when the Sigma Meter reaches 100%. Wipes swarms and deals heavy damage to bosses.
Broadcasts hypnotic purple CRT radiation across the facility, completely freezing all toilet enemies in place for 6 seconds.
Drops a massive sonic shockwave that knocks the entire enemy vanguard backward and inflicts concussive stun.
[H] opens the Alliance Barracks to recruit defenders. [S] opens the Weapon Shop to upgrade automated laser/rocket/turret defenses.
