The Red Lantern is all about surviving the Alaskan wilderness. The same goes for your sled dogs, which might meet an untimely end depending on your actions. If that's too much for you to stomach, no worries. The developers have included an option that does away with that mechanic completely.
When you start up the game, the options menu presents you with a setting called "Dogs Always Live." As you might suspect, this means no matter what happens in the game, your dogs will always survive. Including this options is sure to convince a few more players to pick up the game, and those looking for the more traditional experience can go without.
