Save after completing the main game (including in heroic mode) and Subject 2923. Save for those who want to start the game (build 248587) as a super mega character. Class: hunter, but the luggage I collected will allow me to play in any style. In the single-player game, I seem to have collected as much as I can (see screenshots). Although I am sure that there is room for growth.

If you wish, to complete the training, go to the mission “From the Ashes”, where you activate the huge crystal. Delete your save (you can save it somewhere), replacing it with mine. Path: C:UsersUsernameAppDataLocal. Login to the game. Here is the mentioned crystal. Open it: World Settings - Campaign - Restart Campaign (select difficulty mode). Get the start of the "From the Ashes" mission with all the goodies.

There is a second heroic mode character. Still that tough guy. Whoever you want, continue to be a hero.
