Workshop › Missile Command-style Defense › Step 28 of 35

The end

What we are doing

When the last city falls, the game is 'over': nothing moves any more. And you can only fire while playing.

```js
if (state === 'over') return

if (!cities.some((c) => c.alive)) {
  state = 'over'
  return
}

if (state !== 'playing' || ammo === 0 || ty > BASE.y - 10) return
```

What it means

• At the top of update: when over, do nothing.
• !cities.some((c) => c.alive) is true when no city is alive: the game is over. return skips the wave-end bonus.
• fire now also refuses when the state is not 'playing'.

Your turn

1. At the very top of update, above the between block, write if (state === 'over') return.
2. Above the wave-end if, write the lost-cities block.
3. In fire, add state !== 'playing' || at the start of the condition.
