Players are able to choose between Standard or Hardcore difficulty, and the rewards gained will most certainly exceed expectations. You’ll gain more income over what you normally do in standard PvE. There are also achievements to earn, which grant decals, camouflage, and much more.
Other updates coming along with 0.23 include a new PvP map, grassy fields, night battles, AI opponents for low tier PvP battles, a new dossier interface, and lastly, Epic Medals.
