Backstory
The Farm Alarm Siren was installed for emergencies, and the farm has decided that every single wave is an emergency. It screams. Not rings, not chimes — screams, across a huge area, with the kind of volume that makes the whole field stop what it’s doing and pay attention. Stealth chickens learn what it feels like to be seen. Ghosts learn what it feels like to be stung.
It is the largest sound the farm owns. Where the Bell Tower rings, the siren screams; where the chimes tinkle, the siren screams louder. Its coverage is enormous — 300% range — and its job is simple: nothing on the field gets to hide. The invisible become visible, the incorporeal become irritated, and every tower on the board suddenly has a very clear target list.
Its weakness is honest: low damage. The siren is an alarm, not an artillery — it reveals, it stings, and it lets everyone else finish the job. Bigger Bells makes the scream hit harder, Royal Bells makes it scream twice as fast, and Rapid Fire keeps it wailing. The farm’s neighbours have stopped asking about the noise. The farm’s neighbours have learned to live with the truth.
What it’s good at
Enormous coverage that reveals stealth — the whole field hears the truth.

Power-ups & upgrade paths
📈 Perks that boost it
Bigger Bells, Rapid Fire
✨ Relic synergy
Royal Bells — bells ring twice as fast.
🔱 SUPER fusion
Eight of this defence fuse into one SUPER unit — x10 damage and double lifetime. Only one SUPER on the board at a time; extra sets feed it to power it up.
🔧 Upgrades & buffs
Hover a tower and press U for +25 seconds of lifetime per level. Overclock boosts all damage and fire rate by 50% for 25 seconds, and when the door drops below 15% HP every tower fires 25% faster. Press H for buff mode — towers beside a SUPER boost it 5% each.
Durability
💥 Smash hits
6 hits before it falls apart. 6 smash hits and the siren finally goes quiet.
🍗 Who smashes it
Demolition Drumsticks take 50–75% of a structure’s max HP per swing, and Heavy Metal Chickens and Bureaucrat Elites knock things down too.
☢️ Friendly fire
Your own Nuke and explosive chain reactions don’t care whose side it’s on — keep fragile towers out of the blast radius.
