The exact details are going to be revealed more on Saturday but essentially it seems like.... Dust players use the same currency as Eve players and both can sell and buy from each other and set contracts up... so dust players can put contracts up for Eve players to pick up to support them on the ground and Eve players can contract Dust players to attack planets (not clear how that will exactly change Eve right now). Theres a new mod of Battleships (maybe caps too?) for orbital bombardment, so the BS can move into orbit and the Dust players can designate places to strike on the ground. There could be more than just you that is trying to complete that contract which can lead to an orbital fight.... or the opposite side of the war on the planet could have contracted another Eve corp and again, space fight! Its amazing seeing both games sync up in real time. Well... its amazing to me
The loadouts are also very similar to Eve. You get powergrid and cpu and similar mods to implant into your.. uhm... battlesuit? and vehicles. Theres also a passive skill system like Eve but also an active XP style one - not much details on either right now. It also seems like maybe Eve players will be supplying the vehicles to the land fights too... or at least can bolster the fight.
Its all just really cool and really interesting. Eves already pretty much one of the most unique games around (love it or hate it) and this is just pushing it farther.... if it works. I was really cynical of it all before that presentation but now I'm all excited! You cant know till you play it and see how it feels/plays but... yeah.... GIVE!
Sounds like it will be very late this year or early next year.
