Hi! Glad to meet you!
1. Our game definitely will have PvE, but not canonical story mode or campaign.
Imagine a galactic map inhabited by warring factions, pirates, mercenaries and thousands of other players, each with their own agenda. There are thousands of star systems to explore for you.
Test your fleet in PvE missions and raids
Each section of the galactic map has its own assortment of randomized missions.
Whether it’s escorting a diplomat to another planet or fighting off pirates that have been harassing travelers, each mission provides an opportunity to test your tactics and improve your fleet. Successfully completing these tasks will give you rewards in the form of currency, resources and equipment.
There are also epic, raid-like missions that you can do with friends or other spacefarers. The rewards for completing them are higher, but they will require team work and coordination if you want to stay alive.

2. It will be pure online.
3. In game shop you be able to buy ship skins, special ship bundles, some XP or resource boosters and some other cool things. But we hate "pay-to-win" experience in free to play games, so we try hard to avoid it.

Feel free to ask more ;)
