Just spotted on the appstore that due to our new worst enemy Covid-19, Ironhide has made the following Kingdom Rush games free: Kingdom Rush Kingdom Rush Frontiers Kingdom Rush Origins Both phone and HD versions inclusive.
I don’t know. These are on sale all the time. On top of that, even those premium versions has a lot of IAPs in it. I’m not a fan of tower defense genre, so I’ve never played any of these (and I’m not planning to), I’m just saying from what I’ve seen on the App Store and else. I understand these are wildly popular, so if it’s your cup of tea, this would be as good time as any to grab them and try.
You don’t have to look at the in game IAP. those games are tremendous, and also the Vengeance chapter is incredible. You should just play them and enjoy them
