Tower Defense Game
The name of the Desktop Tower Defense game says it all. Little enemy dots will try to cross the screen to safety. To stop them, you have to build different kinds of towers. You’ve got slow, long-range missile towers, rapid-fire towers, towers that slow enemy movement, and so on.
You can’t really win the Desktop Tower Defense game, unfortunately. Different arrangements of enemies continually file into the kill zone, with each new set being a little tougher than the last. Eventually no amount of firepower can stop them and, once you’ve let 20 through, the game is over. No ultimate victory; just the highest score you can manage.
I’ll let you in on the secret to getting a high score, though. Every tower secretly serves a dual purpose, raining death down upon the enemy as well as blocking movement. Once you learn how to set up your towers to route the enemy along a dangerous, tower-lined path, you’ll be able to take them out much more efficiently. Doing this, I managed to get a score of 1458 on normal difficulty. Give it a try. Trust me, it works.

Okay, so I haven’t got the perfect strategy yet, but here’s a tip to winning at Desktop Tower Defense: Less is more. A single typhoon tower (i.e. a fully-upgraded squirt tower) can easily annihilate a whole wave of enemies on its own. Sure, it’s costly, but you’ll get more out of two or three upgraded towers than you will from entire rows of lesser towers.
