The king has exiled his brother for treason (or so we are told). You are an army General returning from a long trip, tasked with defending the kings city against his brothers attacks. In this min-max resource management tower defense, you will die...Eventually. There is no end to the eternal waves of attacks and no breaks between waves. Can you survive the human extinction era and reach the leaderboard?
Min-max the resource systems and discover the fastest, most efficient resource upgrade path. Efficiently transition to new resource systems as they unlock through the human eras.
There are no wave timers, no breaks between waves - the armies keep on coming, and they will never stop until they take back the city.
Upgrade your spells to compliment your towers, keep up with the waves, or boost your income. Feeling behind? Use your panic spells to buy some time and a chance to catch up, but be careful as they are rare.
