Most of the games are just boring. It had some minor highlights, but it's really not a worthwhile experience overall. Just watching a YouTube playthrough should be more than enough.

Edit: Just realised that Shatter is in this, and not Dread X Collection 2. 'Shatter' deserves to be a full game — it has one of the most intriguing premises of any game within the past decade (as fas as I'm aware). I still think the collection is not worth buying just for this one short game, but it's something to note.
