The same as Knock on Wood, On Thin Ice and Spring is in the Air, you have to use your Launcher to attack the Pigs. Take a Level Card and build the level using the Wood, Glass and Stone Blocks. There are 5 difficulties of the Levels. 1 set says 1 (PB) for Pig Bang. 2 (CC) for Cold Cuts, 3 (FMTTM) for Fry Me To The Moon and 4 (U) for Utopia. An extra one, saying E is for Eggsteroids. In your levels, you can earn 8 Eggsteroid Levels. 2 Eggsteroids are hidden in Pig Bang levels, 3 in Cold Cuts, 1 in Fry Me To The Moon. And 2 in Utopia. Also, Danger Zone is not included with this set. After completing Pig Bang and Cold Cuts and Fry Me To The Moon, you can battle Fat Pig in Utopia! That is why a seperate unfrozen version of Fat Pig is available.
Conclusion: I love this game. I bought it on my iPhone the day it was released, and I've been playing it ever since. Interestingly enough, I finished all of the standard levels in a couple of days. I've been stuck in the Danger Zone for a while now, as its proved more challenging than I thought it would be, given the rest of the game. In Angry Birds, purchasing the Giant Eagle for $.99 gives you unlimited use of the bird, but only once an hour. In Angry Birds Space, purchasing the Giant Eagle for $.99 gives you 20 shots, and then when the bird warps out of its worm hole, it's very possible that it doesn't crush everything like it did in Angry Birds. If Rovio was having revenue issues with Angry Birds, its seems to have solved that problem with their difficult Danger Zone and revamped Giant Eagle. This, however, won't keep you from hours and hours of enjoyable game play. This is perhaps the best Angry Birds yet.
