Survivalist

You start with three survivors and one highway. Each gate is price extra the longer your squad shoots it — maintain fireplace on a `+1` and watch it climb to `+20`. However gates come in pairs with a deadly pillar between them, so you have to choose a side: the `&occasions;3`, or the `+18`, and never the `÷5`. Break green crates to hit more durable and blue ones to shoot quicker, dodge every little thing stable, and kill what's coming down the lane. Every stage ends with a boss. Die, and it comes again weaker.
