Kingdom Rush 6: Genesis TD – Mobile Vibes
There was a time when I really liked mobile gaming. Back in the early days of the original iPhone, before everything became free-to-play nonsense and every five minutes involved someone asking me for money, mobile games could feel genuinely exciting. Kingdom Rush 6: Genesis TD reminds me of that era. It feels like a proper old-school mobile game that has simply wandered onto Steam, complete with everything you’d expect from the genre. And while it doesn’t exactly reinvent tower defence, it does deliver a solid and enjoyable example of it.
Back To The Beginning
Kingdom Rush 6: Genesis TD takes the series back in time, with the story revolving around stopping Vez’nan before his corruption takes hold and changes the future. The story is perfectly serviceable and gives you a reason to move between the different stages, although let’s be honest: we’re mainly here to build towers and stop enormous waves of enemies from ruining our day. The campaign takes you through different landscapes, with 18 stages to work through and plenty of enemies, bosses and other challenges along the way.
Classic Tower Defence
If you’ve played a Kingdom Rush game before, you’ll know exactly what you’re getting. You start each level with some money, choose where to place your defensive towers and then watch the enemies start marching towards your base. You’ll have the familiar mixture of towers, including ranged attacks, warriors and artillery, with new towers becoming available as you progress. Different enemies have different weaknesses too, meaning you need to think about which towers you’re placing where rather than simply covering the map with whatever happens to be available. Defeating enemies earns you more money, which can then be spent on additional towers or upgrading the ones you already have. It’s a simple formula, but it’s a formula that works.
Heroes And Spells
There are a few additional toys to play with too. Heroes can be placed directly onto the battlefield and moved around whenever you need them. You can use them to plug a gap, deal with a particularly nasty enemy or simply reinforce an area that needs a little extra help. There are also spells that can be used during battles, giving you another option when things start getting a little hectic. Between stages, you can upgrade your towers, heroes and spells through their respective skill trees. There is a satisfying feeling of gradually making everything stronger, although it does mean that some of the later content can feel like it expects you to have done a fair amount of upgrading and grinding.
Three Stars And A Bit Of Grinding
Each level has a three-star rating, encouraging you to go back and replay stages to improve your performance. This is where I found myself having slightly mixed feelings. The game can be quite grindy at times, particularly early on. Some enemies can feel surprisingly tough before you’ve built up enough upgrades, and I occasionally felt that I was being encouraged to go back and replay previous stages before I had the tools to comfortably progress. Once your upgrades start coming together, though, things improve considerably. There are also additional challenges and game modes for anyone who wants to squeeze more out of the experience.
A Small Hero Problem
One thing that did irritate me occasionally was the behaviour of some of the heroes. You have direct control over them, which is useful, but if you stop paying attention, they can sometimes stand around while enemies attack them rather than automatically reacting to what’s happening nearby. It meant I had to manually reposition them fairly frequently, which could be frustrating when there was already plenty happening elsewhere on the map. It’s a small issue, but when you’re trying to manage several things at once, it becomes noticeable.
Colourful And Cheerful
Visually, Kingdom Rush 6 looks exactly how you’d expect a modern Kingdom Rush game to look: colourful, bright and full of character. The maps have plenty of little details going on in the background, with villagers, workers and other activity helping each area feel like more than just a battlefield. It isn’t going to revolutionise tower-defence visuals, but the presentation is pleasant and fits the light-hearted tone of the series nicely.
Conclusion: For the Kingdom
Kingdom Rush 6: Genesis TD feels like a nice reminder of when mobile games could simply be good games without constantly trying to sell you something. The Steam version also avoids the sort of monetisation that has made me increasingly wary of the mobile gaming space. If you already love Kingdom Rush, there is plenty here to enjoy. If you’re new to the series, this is a perfectly accessible introduction to the formula. I did find the grinding a little heavy at times, and the hero behaviour occasionally got on my nerves, but underneath that is a solid, enjoyable tower-defence game with plenty of content. It doesn’t push the genre forward. But sometimes a good tower-defence game is all you need.
My Final Verdict: I Like It.
