Apart from being a teaser for the general storyline of the EVE Online: Incursion expansion, the return of a vengeful Sansha Kuvakei and his utopian vision built on cybernetic slaves, it also includes a few interesting things.
First and foremost, Sansha himself is rendered in-engine, a teaser of the character creator coming in the third portion of the EVE Online: Incursion releases in January, which is built on CCP’s Carbon Technology Platform.
There are also other interesting parts including anti-aliasing (a quality of life feature coming in Incursion), the Noctis ship (the salvaging vessel coming in Incursion) taking a beating and of course the Sansha ships themselves, which will be invading systems at random and provide group PvE content for 20-40 pilots at a time with awesome rewards.
