Tower defense games, a genre as old and time-tested as... well, at least that one mod I found for Warcraft III back in the day. At any rate, tower defense games seem a dime-a-dozen these days, especially on Android, but a strapping young whippersnapper looks to be the king of the heap.

For those of you who've played Robo Defense, you know it's the grandaddy of tower defense games on Android. Take Robo Defense's core gameplay mechanics (or any tower defense game's gameplay mechanics) and slap the shiniest, smoothest, most excellent graphics on them you can, and you've got Fieldrunners HD.

From a mechanical standpoint, Fieldrunners HD plays just like any other tower defense game. Set up towers (of which there are many), pew pew the bad guys, and earn monies for it. With your newly acquired cash, buy more towers, pew pew the bad guys... You see where I'm going with this. It isn't a bad thing Fieldrunners HD doesn't change the game, because the formula works. It's still fun.

The biggest selling point for this puppy are the graphics. Man, are those graphics gorgeous. I know it sounds like I'm blowing it out of proportion, but I can't get over it! You're looking at an early-days Android user who lived and breathed Robo Defense. When Robo Defense got a graphical overhaul not too long ago, I was pleased. But man, it doesn't touch Fieldrunners HD.

You've got full body motion on the troops you're trying to mow down, sound effects enabled by default, and at least on my device, not a stutter to be seen. You can even throw the whole round into 2x speed and it'll run like greased lightning. Like butter. Pick your cliche, cause it's good.

Other than that, there isn't much more to say. You've got three modes of difficulty, so start off easy to make yourself feel good, then ramp up the difficulty and watch the computer field-run circles around your vain efforts to shoot them down. It builds character, I hear.

Fieldrunners HD runs $2.99 a copy, which is an absolute steal for something this polished. It might be a bit more expensive than some other games in its genre, but they're not offering what Fieldrunners HD is offering.
