If you've been waiting for achievements, we have good news: your wait is over!
There are 10 achievements so far, with more to come in the future. If you've already completed chapter 4, all you need to do for any achievements you've earned to pop is to load the last save and advance into the credits. You should see those achievements come up immediately.
To avoid spoilers we've made the achievements hidden. But if you want a full list, feel free to join us on Discord. We have them listed in the Heaven's Door spoilers channel.
