Fantastic game

Previously I had left a negative review complaining about how a commander had become pay to use. I suggested that they be included in the free pass so people who are unable to pay real money on the game can at least get a chance to use them. I’m sure they didn’t do it because of my review but this is exactly what they did. This game is extremely fun and I would recommend it to anyone who enjoys siege games.

Fun but major flaws

Overall I have a great time playing this game. I can’t give it more than 3 stars because of how the developers went about the “idle” part of this game. There’s a 2 hour cap on the money gathering and damage dealing for this game, opposed to nearly every other game in this genre having no cap. This isn’t a problem in the first few levels, it’s when you get beyond those few levels it becomes apparent. The little amount of gold you earn per minute combined with the 2 hour cap leads to spending multiple days to get through parts of stages, not even the whole thing. For some people who are able to get on every 2 hours this may not pose a problem but for people like me who work and play these games because I get to see the progress it’s made while in my pocket over the 8+ hours, it’s frustrating and almost a deal breaker. Compounded on that issue is the fact that you can pay to increase the offline time but it’s $4 for only 3 extra hours. Anyone doing simple math can see that buying that 7 times will only get you to 23/24 hours so for the last purchase of another $4 you’d only get 1 hour. $32 for 22 more hours is a ridiculous amount.

TLDR: fun for a bit but be prepared to be frustrated by the extremely slow progress in later stages and the expensive micro transactions.

Hello! Thanks for sharing your review with us. Please note that you can increase gold income by completing contracts. The game allows a relaxing playing mode, where each player chooses his tactic. Moreover, don't forget to level up your commanders, use artifacts — they'll give you additional powers and boost.


Addicting but just a cash grab

TLDR: Fun idle game mechanics that are overshadowed by mechanics that are designed to make money on a quick player turn around.

I have sank way too much time into this game. It’s overall design is addicting and a great time passer. It’s major flaw is how it goes about micro transactions. I don’t think there is anything wrong with micro transactions in a free mobile game but the are extremely under valuing in game. This biggest example is the ability to pay for no ads. You pay $4 for TWO WEEKS of no ads. Why not just raise the price to $10 and make it last forever. It’s specifically punishes players who don’t drop the game after a couple weeks. So let’s say you pay your precious real life money and buy the no ads subscription. The amount of ads you get to skip are ridiculously low for the price. It seems worth it until you get to world stage 4 and the amount of “free upgrades” your getting are so minimal. Please developers, reward your consistent players with a system that isn’t so pushed towards making a quick buck off of new players.
