Offline Friend Invites

[Autisticschwitz]

Allow players to invite their FRIENDS (not random other players) in the Offline Raid menu so that players may practice strategy and teamwork on maps without the dying and losing all the juicy delicious loot they brought with them.

afaik it was planned but discarded soon after because of some issues around the game being pirated because of it being offline?
In that case, may the online mode would switch to "practice mode" and then let you invite friends. It should stay online to avoid this pirating thing, and create a private stance of the game with your friends.
