Rooted by its rich story and dazzling presentation, it's something that every casual gamer should check out.

Mofuya Defense is an excellent addition to the tower defense genre, featuring an upgradeable base that can defend itself, and a balanced power resource management system. With cute pixel graphics, a comfortable learning curve, a good number of weapons at your disposal, and additional features not found in other tower defense games, Mofuya Defense is definitely worth investing some time in.

The latest real-time strategy game from tower defense master David Scott sets you in deep space, defending your asteroid mining operation from humongous swarms of space pirates. The freedom of building in two dimensions gives you a lot of room to experiment and find your own strategy, and the sheer scope of the massive battles make it feel like quality space opera. Constant tension plus simple controls plus nearly unlimited mathematical depth equals awesome strategy game.

Mushroom Revolution is a cartoon-styled strategy game rooted with the tried-and-true tower defense formula, with a simplified elemental tower system similar to last year's hit, GemCraft. A sequel to the obscure Mushroom Farm Defender, Mushroom Revolution is actually more of an updated an improved version of the original, with better graphics and bigger gameplay.

Eternal Red is, by its own admission, a cross between a platform arena style shooter and a real-time strategic defense game. No story, no dialogue, just you and the seemingly non-stop litany of enemies appearing from one door that try to make it to the second.

Viking Defense is a close cousin to Canyon Defense, a re-think of the tower defense genre that was released earlier this year. Game elements are introduced incrementally through a quest system. Once you build certain temples to the Norse gods, you get to use rechargeable powers, like the nuclear super-strike of the hammer Mjolnir. Fans of Canyon Defense will be happy that everything has been improved--the artwork, the map layouts, the weapon variety, and the overall game balance.
