So Kingdom Rush: Origins was pretty fucking fantastic. Best tower defense game I've ever played. Seriously ever. It's so much fun. The way in which it keeps you active and maintains your attention is just sublime. Addictive as hell. It's a little too short though. I completed the campaign in only three or so sessions. I downloaded Kingdom Rush: Frontiers to get another tower defense fix and unfortunately that game is nowhere near as good as its sequel. It's inferior in every way. Anyone know if the original is decent?
I'll be keeping an eye on that studio though. They created probably the most enjoyable mobile game I've ever played.
Yeah, the Kingdom Rush games are pretty much the only Mobile games I play with any regularity. I personally think they are all pretty equal in terms of gameplay, but they do get a little better (or at least different) with each game.
The first game doesn't have permanently upgrading heroes, they upgrade from level 1 in each stage, which gives you an incentive to put them in the action to level fast so they are strong enough for the later rushes of enemies. Frontiers added more of the dynamic levels were new routes open up and there are special towers to spend coins on (pirate ships that fire on enemies, special unit towers on the map, etc.) and added the persistent upgrades for the hero characters. And finally Origins added the Hero Ability that you can activate on your own.
I barely see them as seperate games at this point since I've played them so much, they're more like expansions of the same great game. If you want more content, you can do the two challenges for each stage which gives you enough points to finish up the upgrades on your main skill tree (for the different units and stuff) which then gives you enough power to do the really hard (free) DLC levels they added after release. And then you can play the game on the harder difficulty levels as well. I've seriously put in dozens of hours across these games (woudn't be surprised if I've broken 100 by now) and I still haven't played above "Casual" difficult which feels perfect to me. I did replay the games a lot when I lost save progress on Android, and I bought them all on my iPad as well and play them on there too.
