About

Inspired by the Ancient TD custom map from Age of Empires 2 - but with an evolutionary twist and in 3D. Start in the Ancient Greek era and defend your way through the human eras (Roman, medieval, modern, etc). New spells and upgrades unlock as you progress through the eras, but so do the enemies. Can you survive the extinction era?

Min-max resources and upgrades

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.

Never-ending assault

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.

Use your spells wisely

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 get a chance to catch up, but be careful as they are rare.
