Angry Birds Seasons lets you play the popular birds vs. pigs game, but with themes that match every season. You can play among jack-o'-lanterns and white-sheet ghosts in the fall; snowmen and Santa-capped pigs during the winter; or brightly colored eggs and bunny hats when it gets close to Easter. You can play whichever season you want right away--you won't need to unlock every level in order to unlock new themed worlds. With that said, the gameplay is no different than you've come to expect with Angry Birds, but maybe that's a good thing--most people love Angry Birds exactly the way it is. Like the original, you'll be presented with a structure filled with evil pigs. Your job is launch different types of birds from a slingshot, in the hope of knocking the whole structure down.
Just like every Angry Birds game, the plot is the same: The evil pigs have stolen our avian heroes' eggs, and now the birds are ready to get their revenge. At this time, Angry Birds Seasons includes six different seasonal themes to fit Christmas, Valentine's Day, St. Patrick's Day, Easter, a summer picnic theme, and Halloween. Many of the new levels can be quite challenging (it's clear Seasons was meant for experienced Angry Birds players), so we recommend that newcomers to the game start with the original Angry Birds.
Overall, if you're already an Angry Bird fan, Angry Birds Seasons gives you a bunch of new levels to solve with fun seasonally themed levels to play through.
