I found this information online:
The final chapter in Adera’s first season, Episode 5 – A New Light, is finally available! This episode is by far the largest and most epic in the series. We’ve spent a ton of time polishing it and making it awesome for you, so if you’ve played the previous episodes be sure to grab this season finale and let us know what you think. To gain access to the new episode just update your app if you already have it, or download it from the Windows Store if you’re a new user.
If you’re new to Adera, this release also features a Collector’s Edition which gives you access to all 5 episodes of the season at a discounted price and an in-game strategy guide for each episode. It also includes some extra features in Adera’s main hub, including special backgrounds, wallpapers, music tracks, concept art, and a gag reel. This is a great deal for newcomers, and is appropriately discounted for those who have already purchased some episodes of Adera.
If you have the Collector's Edition, it states that there is an in-game strategy guide. Is that what you have? It sounds like the strategy guide should be in there somewhere. Maybe someone else will know.
