Zombie!
In a brief text message exchange my brother put it rather mildly, what is it with all the zombie games. Now not being much of a horror buff, it has kind of put me outta the loop when it comes to zombie, and I have ventured into a few more mild ones.
After burning a few hours on the game Zombieville, on my iPhone, I realize it could be a fairly addicting game, you can come at it from a few different ways, either you kill as many zombies as you can to upgrade all your weapons or you just run through trying to get to the highest level you can. My suggestion try it one way then the other, you quickly learn strategies to push them back and manage the mobs.
On a More G Rated level I recently downloaded Zombie Vs Plants for my Mac, now this game is published by the company that brings us so so addicting games as Bejeweled, PopCap, as soon as I saw the name I became slightly worried because I now what kind of time vampire PopCap games can become. Being a giant fan of tower defense games it was fairly easy to catch on, basically you have plants with all kinds of special abilities, by collecting sun you can “build” new plants to defend your house from the zombie attack. After spending a couple hours with this game, I have to say its is well worth the 20 bucks, just try it out they offer a 60 minute demo that will give you a good feel for the progression of the game.
