Qube Kingdom from DeNA is a tower defense game. It's also a celebration of the letter "Q." No, seriously, that long-tailed rascal is everywhere in this game.
Unique use of "Q" aside, Qube Kingdom plays like a standard tower defense title with a couple of interesting additions. First off, every structure and character is built out of tiny cubes, lending the world a unique and whimsical look. Second, killing off enemies (also built of cubes) helps fuel traps that can be used offensively and defensively.
Qube Kingdom takes place in a cubed medieval kingdom swarming with undead monsters like spiders and skeletons. Players command an army of long-range and melee attackers, including witches, warriors, barbarians, archers, healers, and more.
Enemies march in from one side and exit out the other. If too many slip by, it's game over. However the good guys can only be placed at designated points, so players need to think carefully about who should go where. Warriors that get axed by the forces of evil come back after a short respite on the ground, but even that brief nap can prove disastrous.
Luckily, players can make use of traps that fill up with cubes whenever an enemy dies nearby. When a trap is filled it can be triggered to devastate incoming enemies with a wave of fire, or it can erect walls that force the invaders to take the long way around - preferably through a corridor filled with archers at the ready.
Qube Kingdom is pretty gosh darn cute (though there is creepiness at hand, too - dig that delightful "squish" when spiders get beat up), but other than getting to fill and manipulate traps it plays like a standard tower defense game. More specifically, it plays like a standard free-to-play tower defense game. The difficulty ramps up quickly, and the player's best bet for success is to grind out previous battles for the cubes necessary to upgrade their army. Of course there's always the option to spend real cash to buy gold cubes capable of summoning powerful rare warriors to fight on the side of good.
Despite its neat graphics, Qube Kingdom is likely of greatest interest to anyone nostalgic for simple, straightforward tower defense gameplay. Just prepare to buckle in for some grinding, or break out the wallet. Whatever works!
