Is this going to be a DLC for APOS or a completely new game in the series?
Its new game, branch from APOS to "Western Front" but with a very long detour
Successor of APOS it will be something like AP:<Summer 1943>
- What are the main changes you are making?
All that enter into the appropriate patch for APOS (or it sucessor) at release moment.
- Can APOS operations and DLCs be imported to APN?
No, Nomongan dont have any vehicles or soldiers from APOS, but landscapes/mod tools/editors will be compatible (I hope).
