Get a quad-core desktop PC for $279.99 shipped

Finally ready to replace that old Windows XP box? Here's your chance to score a seriously powerful system for a seriously low price: Buy.com has the Gateway DX4200-09 quad-core desktop for $279.99 shipped.

I know what you're thinking: too good to be true. But I'd say this system has only two shortcomings, both of them minor.

First, it's a refurb with the typical 90-day warranty. You know my thinking on that: any problem that might have existed with the system has been fixed, so in some ways it's actually better than new.

Second, … Read more

Stop the aliens from taking your sheep!

TowerMadness Zero is the free, ad-supported (and full) version of TowerMadness, a tower-defense game in which you defend a small herd of cute sheep against an advancing army of aliens (who want to turn your sheep into "a new scarf for their emperor").

The game and its interface will be familiar to fans of tower-defense games, with enemies from multiple UFOs attacking across an open plain at first, but then mixing in fixed-path and open-path challenges as the game progresses through 15 maps. You touch the map to build and upgrade towers, and you can use two fingers … Read more

Cityscape wallpaper

This wallpaper features a photo of a silhouette cityscape, shot at an angle from the 37th floor of the Millennium Towers building in New York. The Wallpaper: Cove Towers download includes a wide-screen and regular version of the photo, as well as thumbnails of each photo and a Read Me file that contains information about the location and technical aspects of the photos.

Five awesome iPhone tower defense games

If there's a bigger game genre for the iPhone than Tower Defense clones, I haven't found it. A quick search of the App Store reveals well over 100 titles matching that description.

No surprise there: the iPhone's touch screen lends itself perfectly to this kind of game (which, for the uninitiated, requires strategic placement of defensive armaments to ward off increasingly powerful attackers).

OK, but which TD titles are worth your time--and cash? Here's a roundup of my five favorites. It's by no means a definitive list, but I think fans of the genre will enjoy them all.

Bloons Tower Defense Balloons. Monkeys. Darts. Nearly everything from the beloved Web-based classic appears in the iPhone version. The controls are a little finicky, but if you want to introduce young kids to the world of tower defense, this $2.99 game is the one to get. Navy Patrol: Coastal Defense Though the learning curve is a bit steep and the onscreen action can get a little cluttered, this naval-themed, open-path TD exercise offers some of the most in-depth and challenging gameplay I've found. And the $1.99 purchase price includes new maps as they get added to the game.… Read more

Defend Mars from attack

Sentinel: Mars Defense is a visually rich, science-fiction-flavored, fixed-path tower-defense game, the less interesting--but also less expensive--predecessor to Sentinel 2: Earth Defense. You command the dropship Sentinel, tasked with defending a colony on Mars from seemingly endless waves of remorseless aliens.

Following a traditional fixed-path format, aliens advance up a single (sometimes forking) route, as you use your limited resources to marshal an array of upgradeable towers to stop them across four different maps, making strategic decisions on which towers to buy, where to place them on a grid, and whether to sell or upgrade units. The enemies are largely … Read more

Top Tower Defense games for iPhone

If you browse the iTunes Store for iPhone and iPod Touch games, you've probably noticed there is no shortage of Tower Defense titles. It's probably because this genre seems to be a natural fit for the touch-screen interface. I decided to put together a collection of my favorite Tower Defense games (all rated highly), just in case you've been looking for a new time-waster or just want to sample what Tower Defense is all about.

Check out our collection of Top Tower Defense games for iPhone and iPod Touch.

Defend the dungeon against greedy adventurers!

Dungeon Defense is a promising game with ample swords-and-sorcery ambiance and an innovative take on the traditional tower-defense format. You have to protect a dangerous dungeon, commanding an evil army of skeletons as it fights off heroic (or maybe just greedy?) adventurer types. But the "towers" in this tower-defense game are your skeleton warriors, and the skeletons--being skeletons--they move.

The interface mimics many other tower-defense games: you pick from three skeleton types (light, heavy, and archer), you choose where you want to place them on certain locations on the map, and then you can sell, upgrade, and heal … Read more

Defend against an endless onslaught

FieldRunners is a polished tower defense game with crisp graphics, realistic sounds, and extremely addictive gameplay. Instead of defending a set path like in many games of this genre, in FieldRunners you need to construct your towers in such a way to force the baddies to take the most damage. We had the most luck by creating a sort of maze which forces the soldiers to double back and take damage from the same towers several times. As you progress you earn money, which allows you to buy more towers and to upgrade old ones. You also can unlock maps … Read more
