Great tower defence

Old game that is absolutely amazing. Wish it were still supported. Currently emulating windows in order to play, but it would be amazing if the developer created new games or even supported the older versions on their original platforms (IOS, Android, etc.)

As a fan of the Tower Defense genre, I think this is a great game. The gameplay is addictive, there are some cool features.
Not recommended Dec 11, 2022
One of the few games on Steam where the achievements are literally impossible to complete.

Search Sekiro cheap and the results are keyshop listings, not a store discount. Our three-month price record explains the gap, and why so few live offers changes the advice.
