Here's how to play the first major expansion for hardcore third-person shooter Remnant: From the Ashes
Even if you didn't complete the Remnant: From the Ashes story campaign, but purchased the Swamps of Corsus Bundle add-on, you can start it immediately after installation. To do this, you just need to enter the game with your character (or any character that suits you), then activate the crystal and select the " World Settings " item. Here, select the first item on the left "Campaign". This mode starts the main storyline of the game.
After you have clicked on " World Settings " of the game mode selection, click on " Adventure ", then " Create New Adventure ". Here you have access to four planets, and, accordingly, four different adventures.
In the same menu where you chose Campaign or Adventure, select the rightmost item " Survival Mode ". After that, a menu will open with a choice of difficulty level. We recommend that you first test yourself on normal difficulty, gradually increasing it.
