Summary: Anyone who liked this, i would suggest Defense Grid. To anyone who hasn't played it yet it is a good Defense Tower type of game, which is pretty fun, but becomes tedious pretty fast, since it seems the levels can be passed using only one (designer-predetermined) strategy of turret placement.
Summary: The creators of this series must be well familiar with mottos like "Perfection lies in simplicity" and "Don't fix what's not broken". They really don't try to make ibomber games anything more than just simple classic TDs, and they don't have to!
Summary: A refreshing, casual game which can be played whenever you need to distract yourself. It offers multivariate maps, unique challenges, and upgrades you can apply to customize your gameplay at any level.
Summary: Nice little game. It's one of the more simplistic tower defense games I have played, and I'm pretty sure it's just ported from iOS. But if you are new to the genre and want to learn, or want some light fun on your netbook, it's well worth the $5.
