Bloons Tower Defense 3 has finally been released after months of anticipation from all the hardcore Bloons fans out there. Picking up where Bloons TD 2 left off, the new game features even more tracks (eight in all!), new monkeys (towers) and upgraded gameplay mechanics.

In the simple and kid friendly Tree House Defense, another fun game on Whirled by Three Rings, made by Bill Robinson, protect your tree house from bullies, skateboarders, skunks, and other assorted neighborhood menaces. If you find that some of the elaborate tower defense games are bit too eye glazing and forbidding to get into, then this cute and simple game is a great place to start. So, it's probably not for the seasoned tower defense veteran.

A sequel or upgrade to the original Protector, a tile-based tower defense strategy game focused heavily on upgrading. In fact, Protector 2 has only two basic units; a mage and a warrior (although both can be heavily upgraded into different classes). The mage and warrior both have strengths and weaknesses, the most prominent being the low damage but high range of the mage (and vice-versa for the warrior). But through an amazingly deep system of experience levels, class choices and skills, these two units can be configured into many different sub-types.

Gemcraft brings a lot of innovation to the tower defense genre, quite an accomplishment considering how crowded it already is. The new gameplay mechanics create a lot of strategic depth, and the game adds replay value by keeping track of your high score for each level, allowing you to go back and replay them for much higher scores once your wizard has leveled up and is more powerful.

Harvest: Massive Encounter is a survival-based real-time strategy game with several modes of play that lend a free-form tower defense feel to the experience. You play the humans defending an expanding plot of land against swarms (and I do mean swarms) of alien UFOs, mechanized bots and other baddies. It's an extremely frantic game that's usually more nerve-wrecking than brain-stretching.

Canyon Defense is, not surprisingly, a tower defense game with nice pixel art and that does things a bit differently. First of all, there are no upgrades. What if I told you this heresy against form also has time-based special abilities? And support buildings? If you want some fresh TD with a Mad Max aesthetic, try Canyon Defense.

The pickles are attacking! Run! And while you're running, why not set up a few defensive towers to take out the Horripickles and Fisquitoes chasing you? In Sandlot's latest game, Monster Mash, you must protect storybook villages and their people from evil fairy tale monsters. It's a tower defense game with artwork, characters and plot taken right out of a children's book, and it's every bit as surreal as you might think.

David Scott has just released a sequel to the stylish tower defense game, Vector TD, appropriately titled Vector TD 2. Using Vector TD, a computer simulation of Vectoid attack scenarios, deploy and upgrade towers to zap foes as they walk by, preventing them from reaching the end points on each map. Earn cash by defeating foes and keep your defenses strong to stave off the increasingly powerful hordes!

As evidenced by a flood of Flash-based titles in the last year or so, tower defense games are all the rage. Now, iWin is throwing its hat in the ring with Garden Defense, a full-blown downloadable tower defense game where you save your garden using gnomes, flamingos, cupid statues and a host of plants to fight off waves of attacking bugs. It's eat or be eaten in this easy to learn but surprisingly challenging strategy game!

The first Flash Element Tower Defense was a kind of revolution. It single- handedly brought tower defense games out of the realm of Warcraft mods and into the world of free online gaming, kick-starting a new genre practically overnight. Now that Dave has teamed with Paul Preece to create Novel Concepts, he has built Flash Element TD 2 according to the Casual Collective aesthetic — the audio/visual style pioneered by Desktop Tower Defense and perpetuated by Buggle. In other words, it's totally cute.

Tarnation is a clever real-time strategy game by Brad Merritt that bears some resemblance to a tower defense title. You control a garden with rows of seeds ready to sprout into flowers that will dash off and dispatch incoming bugs. The bugs are made of Tar, you see, and if they reach the stream in front of your flower bed, they start to gunk up the water. Merely defeating all the bugs is enough to pass, but real excellence comes by releasing only as many flowers as you need.

When Orcs Attack is a tower defense game that... towers over other tower defense games. The first title made by Mr. Joy (a.k.a. John Frisby, WOA, pronounced "whoa!") uses the powerful Unity engine to give you powerful 3D characters and particle effects in-browser. Not only does When Orcs Attack play smoothly, but this is a huge technical step-up for web games.

Hot on the heels of the original Bloons Tower Defense game comes a sequel that delivers more of the same explosive fun the original packed, and yet with 3 new difficulty levels and more tower types than ever before. Like the new Road Spikes that you can use to pop any remaining bloons if it looks like some will escape. And the update promises to provide a greater challenge than the first one did.

New from Hero Interactive, creator of Bubble Tanks and Light Sprites, is a unique combination of tower defense and role playing genres (with a little BowMaster Prelude thrown in for good measure) called Storm Winds. Defending the last fort against an oncoming enemy, you must purchase and place turrets on the structure and keep them in good working order. As enemy waves fly in, select a turret and start firing. It's an intruiging combination of game types that's both strategy-oriented and action-packed.

A demo download for Windows only, Immortal Defense is a tower defense game with some aces up its sleeve. It's a game with impressive special effects and a captivating storyline, the latter of which is unusual in the tower defense genre. RPG Creations has put together a long-lasting demo experience should you be brave enough to take on the volunteer mission to fight millions of aliens using only the power of your consciousness.

Toytown Tower Defense is yet another game of the tower defense genre that provides a decent amount of polish and a twist or two. It is otherwise more of the same, but still fun if you're a TD fan. You place towers and upgrade them with money you earn from killing enemies marching on a pre-set path toward your castle, if twenty reach there you lose.

Bloons Tower Defense takes the Bloons concept—popping balloons, preferably with monkeys involved—and spins it in a new and intriguing direction. It's your standard tower defense game but with monkeys popping balloons with darts and various other sharp instruments. It's a flawed but engaging title that is sure to please die-hard Bloons fans.

Harvest is an upcoming game by Oxeye Game Studio currently in open beta. It is survival-based game that combines elements from tower defense and other real time strategy games. Those familiar with either of these types of games should feel right at home.

Protect your precious desktop from the invading enemies by placing towers throughout the screen. Choose fast-firing but weak turrets or slow-but-powerful ones to ensure no creeps cross your borders. Desktop TD features charming hand-drawn graphics and freeform gameplay that make it a winner in the tower defense genre. New in version 1.5 are new towers, enemies, challenge modes, and upgrades sounds and visuals!

As with other tower defense games, you earn cash by obliterating the attackers that creep their way around any one of several maps available to play. With the cash you can purchase additional turrets or upgrade existing ones. But it is the Combos in Onslaught 2 that add a level of depth to this tower defense game not present in other games like it. The combinations are many, and the resulting strategy becomes deep.

Momentum Missile Mayhem plays like a combination of a tower defense game and a physics-based strategy game such as Bowmaster Prelude. Waves of enemies come piling in from the side of the screen. Your weapon works like a slingshot: grab the missile and pull it back, then release to send the projectile flying. There's a lot of strategy and customization built into this game, so be prepared to sink your teeth into a deep and immensely rewarding casual online game.

The latest tower defense game from David Scott, creator of the unbelievably addictive Flash Element TD and Flash Circle TD, has just been released and this one follows a more abstract design for its creeps (called "vectoids"). Vector TD combines vector-styled graphics (remember the original Asteroids?) with the tried-and-true gameplay of David's other successful games to deliver one of the most polished TD games yet.

With the latest Pokemon game consuming much of my idle time lately—and this coming from someone that is definitely not a fan of most RPG games—it has been difficult at best finding something new and compelling to post. However, here are a couple of tidbits to keep you occupied for now (and to buy me a little time for more Pokemon...)

David Scott is back. If you don't recall who that is, you will certainly remember Flash Element TD, David's first JIG-featured title. In Flash Circle TD, you will immediately find yourself at home with similar concepts as before. It is your duty to defend your position against wave after wave of various types of monsters.

For the past couple of days I've been playing this great little warcraft-themed, tower defense Flash game and I am certain there are others that will enjoy it too, but it may not be for everybody. Flash Element TD is a simple implementation of a defend-your-base game that features tower defense structures that are used to repel waves of attacking creatures, or "creeps."

Master of Defense is a simple strategy game about defending your townspeople from the dangerous monsters that lurk just beyond the town gates, and these monsters wish to do them harm. The game is a simplified real-time strategy (RTS) game, and it is downloadable for Windows only.
