[3] Angry Birds 2 became available on classic HarmonyOS AOSP base on June 29, 2021 as HMS Android apk app.

The main enemies of the game are green-colored pigs of varying sizes, who can be defeated using birds, spells, objects or terrain damage.

The slingshot can be leveled up by completing hat sets, providing a score boost to all the players' birds.

Once fed enough times, the player can also level it up, increasing the multiplier bonus and the apples requirements.

Levels include multiple waves of pigs, which progress through separate structures, each one completely independent of one another.

[7] However, lives are not used nor required in the Arena, the Bootcamp or in clan events, which can be played even if the player is out of life.

There are several game modes in Angry Birds 2 other than the regular campaign levels, including the Daily Challenge and King Pig Panic, Tower of Fortune, the Arena, Mighty Eagle's Bootcamp & Clans and other limited-time events.

The Daily Challenge is a set of 3 levels (1 normal, 1 hard & 1 boss) which must be completed all in a row to get the prize.

The Tower of Fortune is an elevator with 60 floors, and functions similarly to the international game show Who Wants to Be a Millionaire?.

After the Mount Everest update, with the same division of players, the Arena became a seven-day-long tournament where the rewards were gems and black pearls instead of feathers.

Although stars are still awarded, the weekly leaderboard is based on the player's total ranking gain.

Once the player's ranking reaches certain thresholds, they will advance to a higher league, featuring tougher opponents, improved win streak prizes and a bigger end-of-season reward.

A player can play the Mighty Eagle's Bootcamp daily and earn points which help them to increase their clan ratings.

A Clan can get ratings on the basis of their players earn points in the Mighty Eagle's Bootcamp.

At the Cobalt Plateaus, while the Angry Birds are sleeping, a Minion Pig approaches and steals their eggs, replacing them with sand bags.

However, as he is about to leave, it is too late, as the Angry Birds have already spotted him, so the Minion Pig tries to escape with the eggs.

Enraged, the Angry Birds (from Red's perspective), launch and start to chase the pigs, rescuing other partners in the adventure, who join them.

The ongoing festivities are also promoted by specially designed levels which gives a premium treasure box in return if the players win it.

Pocket Gamer gave the game a 7/10, feeling that the gameplay was a step forward in puzzle design and the graphics were gorgeous; however, it did not like the energy system that, after failing to complete a few levels, either makes the player stop playing or use gems to continue playing; overall the website thought the game was Rovio at its best.

"[6] Three days after its release, Angry Birds 2 was downloaded over 10 million times; it is a free game on all platforms.
