T-01CIWS
CIWS “Zubochistka”
Front line
The bullet punches through several roaches in a row, and one shot in every few is heavy. Its weak spot is a single target: without a dense column the pierce goes to waste.
Work order #0417 · Site: kitchen · Threat level: high
Shellcrushers, a horde tower defense game
Tens of thousands of roaches pour in at once. Meet them with six turrets, upgrade trees as deep as an RPG and maps that are never the same twice.

01The Office
The end of the world is no excuse to skip the paperwork.
The Shellcrushers are an elite squad of small aliens who already lost their home world to the swarm. Now the roaches on Earth are waking up, and the Extermination Service sends crews in before the humans notice. Clear the site, collect the biomass, file the report in triplicate.

02HQ howitzer
Call in the howitzer
This is the HQ howitzer from the game. Click the floor and it lobs a shell at that spot, and the blast works the way it does in battle. The roaches are heading for the bunker, so don't let them reach it. Shells here are free: accounting will write them off as a drill.

Six turrets, each with its own ascendancies
Each turret can take an ascendancy that changes how it fights: shells that punch through a whole line, rockets that leave a poison cloud, toothpicks that set the crowd on fire.
T-02122
122mm “Splyush”
Against crowds
The shell bursts in a forward cone, not a circle, so you place the cannon with the stream running along the cone. It hits rarely but hard: good against a crowd, weak against a lone roach.
T-03MLRS
“Tarakanus” MLRS
Long range
The rocket climbs and drops on the target after its flight. It can't hit anything close, that's the dead zone. The blast reaches groups a straight shot can't.

Upgrade trees as deep as an RPG
Every turret has its own big tree of upgrades with branches and builds to plan. Between runs, spend what you scrape off the roaches and shape each turret your way.
