Desktop Tower Defense 1.5

As an avid player of tower defense games, I’m pretty selective when it comes to the TD games I return to over and over again. Desktop Tower Defense 1.5 is one of those–the whole series is awesome, but the first version I played was 1.5, so it has a special place in my heart.

Basic Gameplay

You receive a fixed amount of money to start the game off–80 gold–which allows you to buy as few as 2 towers (a Frost and a Dart tower) or as many as 16 Pellet Towers. It all depends on what you want to defend yourself with.

The little green box,
made by your cursor,
shows where you will place
your tower if you click.
The range of the tower
is the orange outline.

If the little box is red,
it means it’s overlapping
another tower, or you don’t
have enough money to build it.

When you’re all set up, hit the “Start” button, and the first group of enemies will appear!

I’m on ur desktop, killin som doodz.

With every group of enemies (collectively called a “creep”), you will receive gold for defeating each enemy within the group. (In the screenshot above, you can see a red “+2” in front of the towers. That’s where an enemy has just fallen, and the game has given me +2 gold.) Then, you use this money to build/upgrade your towers so that they can take down progressively stronger creeps.

Select a tower by clicking it. Its information will appear in the tower selection pane to the right. In this screenshot, I can click the green “Upgrade” button to upgrade my Pellet Tower to a Pellet Tower 2.

This is what it looks like when you’ve chosen to upgrade one of your towers, with the orange progress bar showing you how far along it is. When you’re upgrading a tower, it cannot fire, so it’s best to upgrade between creeps.

Your objective, as noted in the first labeled screenshot, is to keep your enemies from going all the way across the desktop. You can do this by placing towers so that they divert enemies. (A tried-and-true way is to place towers in undulating lines within the desktop space, so that the max number of towers can fire on enemies as long as possible, and the only way enemies can get by is to run along these predetermined paths.)

Also, as the game goes along, the dropped gold from each creep enemy gets slowly bigger (not with every creep, but every few).

I generally buy two or three different types of towers at the start of the game. A Frost Tower is almost indispensable for slowing ground and air enemies, and is wonderful for fighting big clumped-up groups. Also, using a Squirt and Pellet Tower in conjunction with each other is a good tactic to start off with–the faster firing rate of the Squirt tower compensates for the slower Pellet Tower, and the Pellet’s higher damage compensates for the Squirt’s lower damage.

You’ll need at least one Swarm tower to fight air enemies, but you shouldn’t need a line of them. Just make sure your Swarm tower is lined up straight with where the enemies come in, and your Pellets and Squirts should make up the difference.

Dart towers are wonderful for splashing damage–they work well alongside Frost towers, which slow enemies enough for the Dart tower to shoot at them multiple times.

Don’t build too many towers early on; focus on upgrading the towers you have at first, and then start building a couple here and there when you need them to direct creep flow or need the extra damage.

Use all the desktop space given you for undulating lines of towers–don’t make it easy to get to the other side.

Last-ditch effort: Install a few towers on the other side of the map, close to the exit, to catch stragglers. Make sure these towers stay upgraded along with your front line, otherwise they won’t be much help.

Onslaught 2 (Tower Defense)

With several different maps, multiple difficulty levels, and dozens of towers to choose from, Onslaught 2 is one of the most detailed and customizable tower defense games I’ve ever played. Read on, and see why I enjoy it so much!

Basic Gameplay

In Onslaught 2, you are trying to guard the military base (marked “Area 51”) from being invaded by waves of enemies. To that end, you have to build towers of varying types to defend the winding route to the base. If 10 enemies get past you and invade the base, game over. With every enemy you shoot down, you get a certain amount of money, which increases by 1 dollar with each wave of enemies.

This money is for upgrading your towers’ damage, rate of attack, and range–but you have to upgrade strategically! For instance, if you upgrade the tower’s range all the way and forget about its damage, soon you’re going to be pinging away at enemies that barely even feel the bullets, even if you can shoot them from way far away. Thinking and planning ahead is key (see next section for my strategies).

As you progress in the game, shooting down enemies and getting money, you also get access to different types of towers you can build. For instance, you can build a taser tower (temporarily paralyzes enemies), a sniper tower (epic, one-shot damage) and even a railgun tower (zaps the enemy it’s aimed at, as well as all the enemies in a straight line behind that enemy). As the enemies get stronger, you’ll need those better towers to aid you!

My Strategies

I find that upgrading a tower’s damage is of the utmost importance, followed very closely by upgrading its rate of attack. A tower that can shoot for massive damage multiple times in a few seconds is likely not going to need a long range to defeat its enemies. But some players have done well balancing upgrades to damage and rate of attack with upgrades to range; it’s all in what your particular playstyle is.

Though I liked to use the pellet gun tower (blue) when I started playing, I have found that it’s not so helpful after the 100th wave. Likewise, the laser tower (green) isn’t really of much use late-game unless you get a whole chain of them together so they can help each other out. Thankfully, you can sell off older, fully-upgraded towers later on if you need the money to upgrade stronger towers.

As in most games, there are very powerful combos; you can put two or three towers side by side to create much more damage output. I like to use the Rocket (red tower) and the Taser (yellow tower) together–once both their damage output is fully upgraded, they unleash homing rockets that are pretty much one-hit kills for at least 5 enemies. Great for clearing out a clump of baddies!

You can find more strategies and combos by visiting About Combos on the Onslaught website, or by visiting the Onslaught 2 page at JayIsGames.com. One thing’s for sure, there are many ways to succeed in Onslaught–there’s always new things to try!
