After watching the release notice
We can understand it as
1 You can obtain STEAM version testing rights and unique teams by purchasing the early access package
And you can merge the progress of the STEAM version with the progress of the official server.
2 The contents of the early access gift pack (may) correspond to 3 main levels
At the same time, it is guaranteed to be given to engineers and soldiers
This gift bag should be permanent in the store in the future
As the main way for newcomers to catch up quickly
3 It is impossible for the official server to be merged with the STEAM version in a short period of time
this is good news
Because this way there won’t be a large group of old players who rely on equipment advantages to crush newcomers.
4 If you want to join STEAM early and turn those newbies into disabled
you’ll have to buy a new bundle
this is acceptable
Reduce the entry of a large number of old players while showing newcomers how powerful the old players are
