Enemies have a lot more nuanced secondary effects beyond simply attacking your defenders.

The latter is another subtle change for Frontiers.

Another interesting upgrade lies with the Axethrowers (Archer advanced class), which lets you curse enemies to take more damage or dispel aura from the enemies. Mage Towers can now be upgrade to Necromancer towers, which will raise the dead of the baddies to fight for you. For starters, the advanced upgrades for each basic tower have been revamped and are now much more interesting. Where Frontiers does make some changes is in the deeper elements of its gameplay. Otherwise, a full-fledged campaign returns, with Heroic and Iron Challenges adding supplemental difficulty for those that desire it. While you don’t need these heroes to beat or experience the campaign in its fullest, the cooler ones are locked away, leaving some disappointment. Unfortunately, just as before players only get a limited amount of heroes through gameplay unlocking, with the majority requiring IAP. The Three-star ranking and upgrade system also return, as well as a wealth of heroes. Heck, even the four basic tower types return unaltered. This sequel employs the same type of Tower Defense gameplay, art style, and presentation. To put it succinctly, if you’ve played Kingdom Rush, you’ve played Frontiers. Preserving the smooth, well-balanced Tower Defense gameplay of the original, Frontiers adds just enough new content in towers, enemies heroes, and locales to make it another incredible experience. In this regard, Ironhide Game Studio’s Kingdom Rush: Frontiers ($1.99)is the perfect type of sequel for me. When it comes to playing sequels to games that a nearly flawless the first round, my preference is for a follow-up that looks to iteratively improve upon on its predecessors pitfalls without messing too much with its successful formula.
