Hey, no worries about asking! We've discussed this in a couple interviews and in one of our previous discussion topics. The quick answer is that we're not selling loot boxes. We'll be selling additional campaign content in chapter packs and we're considering a few other options (TBD), but we have no desire to compromise the integrity of the game with any pay-to-win schemes or artificial grind mechanics.
We are planning to carry over something similar to the StarCraft II War Chest, where players will unlock cosmetic rewards for completing various in-game activities. We think this can be a good, completely optional way for players to support Stormgate's ongoing development while enhancing the game experience with additional objectives and cosmetic rewards.
