The campaign begins with Arkantos, an Atlantean general, defending his homeland from a Kraken attack. This mission serves as an introduction to basic Atlantean units and mechanics. Your primary objective is to defend the Atlantean docks and then pursue the Kraken. You'll start with a small force of Murmillos and an Oracle Scout. Immediately send your Oracle Scout to explore the surrounding area, revealing resource nodes and potential enemy positions. Focus on training more Murmillos from your Barracks to bolster your defenses. The Kraken will periodically attack your docks, so keep your units positioned strategically.
Once the initial attacks are repelled, you'll be tasked with destroying the Kraken. Gather your Murmillos and advance along the coastline. You'll encounter minor resistance from enemy units. Use your Oracle Scout to reveal the Kraken's location and then engage it with your Murmillos. Remember to keep your units healed if you have access to a healing God Power, or retreat damaged units to safety. The Kraken is a powerful Myth Unit, so focus fire and use any available special abilities your units might have. Victory here sets the stage for the rest of the campaign.
