7. Turret Wars Tower Defence
Probably one of my favourite TD games, Turret Wars does away with all that creep/monster stuff and goes for a nice military feel to everything. The interface is clear and crisp and there’s three different maps to choose from. However, rather than just being a pretty backdrop, this maps have features such as rivers and cliffs which you can make use of to stem the flow of enemies as they free-roam over the map. For the competitive amongst you, there’s an online high score system too!
