Angry Birds Available Now on Facebook with Unique Power-Ups (Screenshots)

Expected to arrive on Valentine's Day, Angry Birds for Facebook has already landed and is available to anyone who uses the site. While the game is the same one you know and love, if you love it that is, there are some Facebook specific gimmicks, like the social aspects, meaning the ability to spam invite your friends to play as well.

There are also bonuses of all sorts, FarmVille style, and power-ups designed to make the game easier, if some level is giving you trouble.

There are four power-ups in total and you get a number of "loads" up front. You'll also be able to earn more, for free, if you play every day for example. Of course, you can also buy them in bulk from the shop, via Facebook credits.

"Power-ups are unique to Angry Birds on Facebook. There are 4 different types of power-ups and they can be accessed via the lightning bolt button at the top of the screen. You can use two power-ups per level," Rovio described the power-ups.

"The four power ups are: Super Seeds, King Sling, Sling Scope and Birdquake. All power-ups have a different effect but ultimately make you more competitive against your friends by making your birds stronger or more accurate or even by shaking the earth itself!," it continued.

Willingly or not, Rovio is revealing one of the main reasons, it hopes, people will buy these power-ups, to better compete with their friends. Granted, that doesn't really sound very sporting. In fact, it sounds like the player willing to spend the most will be the best. That doesn't do much for gameplay, but it's great for Rovio's bank accounts.

It remains to be seen how well Angry Birds does on Facebook, but judging by its previous success and the number of people on the site, the social network may very well become the largest platform for the game.
