Goal and Score

The goal is to reach a certain score before dying to the enemies. Points can be collected by either destroying buildings or killing enemies.

Levels
Each level has a goal, when this goal is reached the player moves on to the next level. Sometimes new levels can unlock defense or offense upgrades. Each level has a certain type of enemies and a different part of the city, starting from a calm farmland with some normal police cars to a city with skyscrapers and tanks. Levels are procedurally generated based on a seed an a perlin noise, each seed has a unique shape, so the environment is different every time you play.
