Yesterday, we announced Sentinel 3: Homeworld by Origin8 which hit the Android market as the third game in a very popular tower defense series, and the first installment to be available for Android. Normally I am not too excited about games of this genre, but I can honestly say that Sentinel 3 has impressed me both in terms of gameplay experience and sheer visual interest, thanks to the cleanly styled environments, visual effects, and smooth animation.
Sentinel 3 has three gameplay modes: campaign, endless, and classic. Each of them is a little different, and they each have their own merits. Before discussing these however we should talk about a few basics.
