Angry Birds 2 is the official sequel to the worldwide phenomenon Angry Birds game.

While there have been a number of expansions to Angry Birds such as Angry Birds Seasons and Angry Birds Rio, Angry Birds 2 is the official successor to Angry Birds, which is arguably the most influential and popular mobile game of all time.

Angry Birds 2 has done an overhaul on the Angry Birds concept while still maintaining the spirit and general concept that made the original such a massive hit.

The first thing that stands out is that the graphics have been upgraded significantly. Backgrounds are lush and detailed, and everything seems to pop out. Visually alone, Angry Birds 2 is a significant upgrade.

One other major change to Angry Birds 2 is that it gives you the ability to select your own birds at the start of the mission. This is a big deal from a strategic standpoint, as you need to weigh your options carefully before the level even begins.

Angry Birds 2 has made some other tweaks to the birds, the enemies and the level structure, all of which refresh the Angry Birds formula.

Anyone who enjoyed the original Angry Birds is quite likely to get hooked by this one too.
