Dual Discovery: Unite Challenge Review

What a lovely “Where is waldo?” kinda type of game. You have to find the 2 parts of an item on the map, combine them, and get the check on the item. For completion you need to find all 18 items in the 9 different levels. Takes around 2 hours to complete.

I love this type of puzzle game where you have to find some items on a level. It isn’t a genre I would play all the time, but from time to time, in between bigger games, it is great. And while some of them can feel a bit stale by now, Dual Discovery: Unite Challenge does something a little different by having to find two items of an object. And I also love that it doesn’t overstay it’s welcome, but is just short and a lot of fun.

For the achievements, you have to find all 18 items on 9 levels. There is an in-game hint system with a short timer to not spam it all the time. This can be used and still be able to get all the achievements.

I give Dual Discovery: Unite Challenge 寻踪觅影：合二为一 4 out of 5 stars.
