All discoveries have been rebuilt. From a gameplay perspective, this should feel the same, although there is more variation in what NPCs do, say and look like!
Ambushes now have discoveries built into them. Like the AIM discovery where enemies appear when you approach only instead of automatically spawning and firing at you, there is a bit of flavor to each ambush which also allows the play to somewhat control when they spawn.
New side bosses! Similar to Mr. Hyde, Kirigi and Batroc in Industry City Patrol, there are new bosses that will spawn as 'side events'. The list is: Black Cat, Man-Ape and Mole Man.
Boss spawns now have a flavor or discovery component. Magneto may be attacking civillians, Doc Ock may be interviewing candidates for the Intelligencia, etc.
Some mob groups have been removed. We want to know if you feel any Legendaries were adversely affected by this.
Population spawners has been tweaked. Again, let us know how it feels.
Performance should be improved! The restructuring allows us to use methods of creating these entities that is less intensive to both the server and client. Let us know how it feels.
