Survivalist

Start with three survivors and a single road. Every gate grows more valuable the longer your squad keeps firing at it — keep your fire trained on a `+1` and watch it swell into `+20`. Gates arrive in pairs with a lethal pillar between them, forcing you to pick a side: the `×3` or the `+18`, never the `÷5`. Break green crates to deal more damage and blue ones to fire faster, steer clear of every solid obstacle, and destroy anything that advances down the lane. Each stage ends with a boss. If you fall, it returns weaker.
