Flash Element TD
Onslaught - tower defense game

There are a lot of Tower Defense games on the Internet these days, most of them use Flash and some are a lot better than others. They are based around a map from Warcraft III and basically involve you using different kinds of defense towers to stop an ever advancing string of enemies. They can get pretty addictive and are a fun way to waste some time, here are a couple worth trying out.

Flash Element TD is a pretty good tower defense game, especially to start out with. It’s fairly straight forward, as you start with 3 basic tower types (which you can upgrade individually) and the new tower types come along at a steady pace, plus the layout gives each tower a couple of chances at hitting the enemies on their way around.

Onslaught is another tower defense game, #1 on some people’s list. Although it may look simple, this is the next step up from games like Flash Element TD. There is a lot more course layouts to choose from and the upgrade system gives you a lot more choice. Not only is there more types of advanced towers to use but placing certain types and amounts of towers next to each other results in big damage bonuses, as you can see on the Combo list. Games of Onslaught can go on for ages, so see how far you can get and compare your score to the High Score list.
