Customer Reviews

Was fun until...

Allow me to preface this review by saying that this game is indeed enjoyable. The castles are customizable, the weapons, spells, and troops are all upgradeable, and (most importantly for a freemium game), it is more than possible to acquire both of the premium currencies without spending any real money.

That said, after I spent dozens if not hundreds of hours dominating pvp (as the overpowered Viking elites) and acquiring thousands of each of the premium and hundreds of thousands of gold (the standard currency), my profile was suddenly "corrupted" and reset to the beginning - thereby wasting all of my time and any real dollars I would have spent, had it not been my personal policy to not spend money on free apps. Regardless, a significant quantity of my time was wasted because of a bug somewhere.

This is unacceptable. If this is a potential hazard of the freemium model, then it ought to be abandoned in favor of paying a dollar or two, and providing real customer support. Frankly, the only reason this even gets one star is because I can't give it zero. If this gets fixed, I will adjust my review. Until then, DO NOT waste your time on this. It may be fun, but to earn something and have it taken away makes it less than worthless.

Second platform I've played this on, love it!

I played originally not that long ago on the Vita. I got it free with PSPlus, and I soon became obsessed! I didn't touch my iPad for 2 weeks as its all I played. Btw, when can we expect a new expansion pack on there? I like playing on the iPad, although not nearly as much as on the vita. Using Garreths bow is tricky and I've not really mastered it or even really figured that out yet. The diamonds are nearly pointless and haven't a clue what the red jewels are for, I imagine it's for pvp. Also, I considered the VIP package for $5, but it's unclear if it's a recurring charge, are the jewels/gold parceled out over time? Do you receive a lump sum then more weekly? It's very confusing and I've avoided it. I've not spent a penny so far, nearly thru the first campaign and hoping it doesn't crash. I've not had a crash yet. Fingers crossed!

Fun and enjoyable until...?

Can't believe I just found this since I play a ton of iOS games on my phone being a college student (don't tell the professor or he'll know my dog didn't actually eat my paper 😏) but I'm definitely glad I found it, better late than never. For the until part.... welp I see some reviews of how people lost all there saved progress by a "corrupted file" which makes me hesitant to even play at all much less put time into it in most part probably due to it being an older game and, I would have to guess, won't get any updates ever again sooooo.... idk if I run into that issue I'll re-review but until then it's fun I just wouldn't get too hooked if I was you 😆
