Casman May 23, 2026
★★★★☆

4/5 because no hand to hand or claw type weapons. Blasphemous. No class, gender locked so that's good. Also, and the best part of the game: customization of skills. Story's okay so far, nothing riveting, but it's a mobile, and thus acceptable. Lastly, monetization is okay, particularly with stash tabs, it's fine, businesses need to generate revenue. But, the cosmetics are atrocious, and it's RNG-gated, so if there's an outfit or whatnot you want, you just got preyed upon.

Im a incredible og childhood 2000s gamer, giving me a dungeon seige 3 slash diablo 2 mix, and it's potential from skill runes and mechanical tech tree is near limitless. it is both free and pay to play. I've gotten 73+ free but im not suggesting dont pay, honestly if this game is takin care of 10 bucks here and there is supportive in my book. 5 stars. on a second note, they should implement a mercenary, 2 inventories, 2 characters, 2 skill trees to work on. with different mercenary selections.

★★★☆☆

I don't give praise to mobile games very lightly. I have to say this is the best. Arp GI have played since Diablo 4, having all of this at my fingertips is great. The graphics are amazing. The combat is fun and the colors are bright. The only gripe I have is with menu navigation. Being absent for controller use, there are so many games that do this correctly. If this had proper controller use with menu navigation, I would give it a 5 star. But for that, I have to knock it down to 3

This should be a 5-star game. This game is by far one of the best, most engaging, and fun mobile games I have ever played. Like Path of Exile on my phone. Except PoE was not pay2win. This is w/o a doubt a micro transaction pit. The game is great. Want to buy an extra storage slot? That'll cost you about 700 gems, which there is nearly no way to make w/o buying them. So you have to buy them. Oh and it's like $20 for 500 gems. So that's a big ripoff. This will eventually kill the game. Too bad....
