Angry Birds Coca-Cola

Angry Birds Coca-Cola (or Angry Birds 可口可乐 in Chinese) was a new game released on June 11, 2012. This version was made with the corporation of Rovio, Coca-Cola Chinese and "The Chinese Olympic Games' Team". The story is centered at the London Olympic Games on July 27. The online version includes 5 levels unlocked already with 2 locked by hitting 40 drums (see below) with another 3 levels locked by getting 10,000,000 points in total. It also includes the first 21 levels of Poached Eggs.

The only birds that appear are Red, The Blues, Chuck, Matilda and Hal.

Nowadays, this game has been removed, and the website redirects itself to the Angry Birds Homepage.

The Drums
There are 4 normal drums and the Golden "Drum o' Doom".

When hit, the normal drums break and give you 1000, 2000, 3000 or 4000, depending on size.

The Drum o' Doom gives 5000 points when broken, but it takes several hits to explode. In the level which it appears, the King Pig is laying on it.
