Onslaught Tower Defense version 2.2 gives you a bunch of strategic interesting maps to defend against waves of enemies. Well balanced game that has (only a few, but) very useful towers.

A great mix of a racing game remade into a tower defense, don't let the cars pass the finish line. A fun game with hero mode.

More fuzzy, fur monsters that attack and need to be stopped in a light themed game.

Instead of towers you need to build lairs that produce troops like goblins, centaurs and vampires. This time you cant build next to the path like you used to do in other games. Give it a try!

Defend against waves of rolling bad guys. Build towers from blocks and upgrade them to bring down the enemies.

War in the backyard. Be the commander of a small army of ants and other insects, build your base and defense to keep the enemy away and crush them. Very nice strategy game with some good features.
