Angry Birds 2 is a lot like the first. You will be flinging at random structures to kill green pigs. Levels will inevitably get harder and harder and you will unlock new birds that do different things. Some will explode while others split into separate birds or fly fast to slam through targets.
The game is, in theory, simple and straight forward. Just chuck a bird through the structure and boom, stuff falls over and pig dies. Later on, however, it gets much harder. You will have to aim carefully to take out supports or push wheeled carts over and take things out that way. The game for me, however, failed to recreate the magic of the first one.
When the first released I remember being infatuated with it, playing for hours and draining my cell phones batter. This one looks better than ever and allows for plenty of customization but I just never had that strong desire to play. The game is fun of course and its good to kill a bit of time with, but for me, it just doesn’t do the same job. By all means, try it, it is fun, but it won’t likely be the nostalgia trip you were hoping for. Best wishes and may the gaming gods bring you glory.
