Truly another masterpiece from Ironhide Game Studios; the game is nostalgic, cool, with amazing levels and interesting enemies, it provides a real challenge, and I love the aesthetic! Standard Kingdom Rush quality, and the Big Hero Pack is great value for money! In my opinion, it's a must if you want the best possible experience, but even without it, you can still have a great time and the game shouldn't be too difficult.

Wow Ironhide, you've done it again! Frontiers is one of my favorite games of all time, let alone mobile! Each level is challenging but has a strategy, great references, creative enemies and something new each stage, as well as a great soundtrack. I'm also glad there isn't a speed up button, as it would be too easy to get overwhelmed. The only thing I'd like to see is easier access to the heroes, perhaps if you could buy them with gems. Otherwise, 5/5!

I played another Kingdom Rush game that was free. It's hard to find solid tower defense games that don't shoot up the difficulty to try and get in app purchases. I I really liked the other game, but it was too short. After trying a number of disappointing free tower defense games, I finally decided it was worth the (very fair) price. And it has been! I've been able to relax and enjoy a game that doesn't punish me to try and get my money.
