EVE Online’s newest content update is apparently so big that developer CCP has decided to split it up into two chunks.
The first part of Aegis will arrive tomorrow, July 7th, and contain a bulk of the new features. These include a new Hecate tactical destroyer, additional SKINs, improved icons, environmental graphic tweaks, and several balance changes to missiles and other combat systems. Missile users should be pleased to see that heavy missiles will receive a healthy 5% DPS bump and ships can store twice as many torpedoes with the patch.
Aegis part 2 will follow a week later on July 14th with a huge update to the Sovereignty system. The patch notes for part 1 are up if you want to get a jump start on the next phase of the game.
