Amid all of the chaos and preparation and aftermath from E3, Kingdom Rush Frontiers, a gem of a mobile game has been released. Kingdom Rush Frontiers is the sequel to the Iron Hide and Armor Games hit Kingdom Rush and came out on June 5. It looks to be every bit as great as its predecessor. Frontiers has much the same basic premise, but offers 8 entirely new towers, 15 new levels, new enemies, new heroes, and new skills. It’s everything that we loved about the original Kingdom Rush, but all brand-spanking-new. I don’t know about the rest of you, but I was just eager to have new levels after going through the last game so many times. So besides being new and awesome, how does it really stack up against the market? Here’s my review of Kindgom Rush Frontiers.
