### 5/5 — A great game.

*2024-04-04*

Im not a really fan of mobile games. Or usually i just get bored of them very quickly. But MK Onslaught is the only game I play every day for the past couple months. I read some reviews where people say its pay 2 play, it actually is not. I have not purchased anything at all (no koins or krystals) the Boss Tower Liu Kang gives you 3 times free money and XP a day and the Scarlet tower gives you the books. You just need to keep playing in the arena and get XP and Coins and then you can buy more krystals or any upgrades etc. in Chasm you can also get a lot of things to upgrade your players. I wish there were more stories. - I guess 1story comes every once to three months. So no complaints at all. Best game, love it love it love it. ⭐️⭐️⭐️⭐️⭐️

### 4/5 — Decent hero collector

*2024-02-23*

As far as these style of games go this one is trying to do it well for sure.
The pricing on micros isn’t insane if you just want to dip a toe into spending, however, FTP players will have a very good way to get gear and progress using the kronicle events every month if you don’t want to spend.
The only place it seems lacking is arena, the rock/paper/scissors style tags they use seems like a good system till you get to the end game arena, then it does seemingly nothing.
I can have a full team of mind characters and still get completely destroyed by a body team that should be easy.
Once you get to the endgame, like most other systems like this, the mechanics matter much less than just overpowering your opponent with high tier characters

### 4/5 — Great game with battery drain issue

*2023-12-10*

UPDATE EDIT: I love this game for having fun with playing it and it is really enjoyable. I am impressed with the story mode, arena fight, graphics effects and eyes catching environments. But there are a big issues with the game. It is quick battery drain down my iPhone. I live in Dhaka city of Bangladesh, and my internet connection is OK with MK game log in based Wi-Fi and mobile internet data. However, last month, I installed the game and played it with login OK. Then after 10 minutes of gameplay, suddenly my phone was heat and hot. I have noticed that my phone battery drained so fast from 100% to 20% for 30 minutes gameplay. This issue has happened because of the graphics and heavy effects. This is why I gave you 4 out of 5 stats. Hey developers, just fix the horrible issue and make a new graphics optimization option and add it to the setting of this game.

**Developer response:** Thank you for sharing your feedback regarding the game's optimization with us. While our game team doesn't reply here, they take these reports into consideration when developing future updates. Should you require any help in the game, do reach out to us over at https://go.wbgames.com/MKhelp and we'll get back to you as soon as we can. Thank you!

### 3/5 — Log-in issue and battery drain

*2023-12-08*

I love this game for having fun with playing it and it is really enjoyable. I am impressed with the story mode, arena fight, graphics effects and eyes catching environments. But there are two big issues with the game. They're Log in issue (of latest version December 2023) and quick battery drain down my iPhone. Despite my internet connection is simply good, after updating the latest version of this game, I opened it and tapped log in. The logging in has been processing for lots of time. This issue wasted my time and my pleasure of playing MKO (Mortal Kombat Onslaught). I live in Dhaka city of Bangladesh. However, last month, I installed the game and played it with login OK. Then after 10 minutes of gameplay, suddenly my phone was heat and hot. I have noticed that my phone battery drained so fast from 100% to 20% for 30 minutes  gameplay. This issue has happened  because of the graphics and heavy effects. Hey developers, just fix these issues right now.

### 2/5 — Boring

*2023-11-11*

I will give the developers credit, they took Mortal Kombat and made it boring. That is an accomplishment. This game is what you would expect from a gatcha game that came out years ago. There are loading times between simple screens. Everything in the ui is obtuse and not user friendly. You want to equip a weapon?  Multiple screens, you have to click on the slot and then go find the weapon you want. Most games now have a simple equip all button. Icons are small and hard to see on a phone and finding out info on what your skills do requires multiple screens, rather than just having them listed when you open up your character menu. You have to look at each one, one by one. 

8 years ago this would have been a below average game, but now if it was not for the license no one would be playing.

### 5/5 — Great game

*2023-11-09*

Ok first of all- lotsa reviews are pointing out little things that don’t affect gameplay at all, it’s a new game, patches and updates will be coming out as needed. Saw someone complaining about needing coins to remove/exchange equipment. The cost is barely noticeable unless your completely out of coins. 
The game is good. Arts great, battles are easy enough to pick up on quickly, pulls are what you expect from a gatcha type game few good, few bad… it is what it is. 
As it’s new I’m sure they will be adding more events and content to make resource collection a bit easier-although they give away plenty, we of course still always need more lol. 
This games definitely worth the play. Try it yourself before you let ignorant reviews push you away!

### 2/5 — Game is good, premium characters too op

*2023-10-29*

This game is fun, love the fact that there’s a whole other story for the campaign. Boss fights are fun and all the other things. 

The reason for 2 stars, because in the arena mode, everyone has these premium characters from lucky rolls, while I have 4 equally leveled characters as well as I outplay them with 3 mind affinity against 2 body affinity’s which is a counter, but I still lose and can’t even kill one of the premium characters the other player has. I try different matchups, most of my characters have max level items but I still lose. I try everyday to try and roll for a premium character but my luck is awful apparently :) . Premium Kung Lao and FuJin are the most OP characters in the game.

### 3/5 — Battery Killer

*2023-10-28*

I’ve been enjoying playing this game this past week and I would like to play even more but wow does this game kill my battery. I have an iPhone 13 Pro and it’s microwaving my phone. Not only does it get hot but the battery is drained really quick to the point where one time I had to charge my phone twice (yeah I was playing a lot lol). Please add a graphics slider so we can choose to wether have good graphics at the cost of battery or lower them a bit and enjoy more battery life. I was really getting addicted to this game but until they do something about the game draining my battery I will not be playing it.

### 2/5 — Sigh.

*2023-10-27*

Originally I had written a massive review that lined out all of my issues. But I’ll just cut it down to the most basic: Micro. Transaction. City. This game is designed to be pay to win. It is designed to take your money. This is not f2p friendly. Genuinely one of the worst cases of this I’ve ever seen. God awful writing. Just. God awful. It makes MK4’s writing look good. This is on par with MK Annihilation’s terrible writing. Remember Sindel’s “too bad YOU will die!”? Yeah this game makes that look Shakespearean. Overtly dated. Same style of game as Street Fighter Duel. But Duel plays like a game developed and made in the last two years. Onslaught plays like it was developed and made around the same time as 11. Because it was. And nothing was changed. WB has got to get it together.
Update: you can’t even refill your event energy for free more than twice total and it costs as much as a pull. Jesus Christ this is embarrassing.

### 3/5 — Has potential

*2023-10-25*

The game itself has good ideas and the graphics and gameplay is quite good. However,  there are many issues with the overall experience. Progression in all ways is terrible. You need different teams of all affinities to get higher in the boss towers which is critical for acquiring upgrade materials when it already takes forever to upgrade your core 4 units. Rewards from dailies and missions are minuscule compared to the terrible drop rates for decent units when summoning and the materials needed to upgrade that unit when you finally do get someone useful. You just end up getting stuck unless you spend a ton of money and then there’s pretty much nothing else you can do. I myself am willing to spend a little and have already, and even still I feel completely stuck. I will stick around for a bit but the game needs some serious changes and better rewards if the devs want people to stick around. Just feels too unforgiving right now. Also, the game will burn through your phone and kill the battery very fast.
