Peggle 2 is Popcap's most recent foray into the puzzle drama and tasks players with playing a pinball-like game where the goal is to reach high scores by hit green, purple, orange, and blue pegs and blocks with a ball that can be enhanced with the powers of the various masters in the game. Each master grants the ball a skill upon hitting a green peg, changing the dynamics of the ball, and the game as a whole, allowing for some added diversity, and the ability for the player to use a power-up that best fits their playstyle. To fit the general puzzle-genre, a majority of the achievements are easily obtained, with a few of the achievements being only obtainable by the best, or most persistent, of Peggle players, testing the skills of Novices and Pros alike.
The initial focus of your time in the world of Peggle 2 will be spend doing the basic levels found in each of the six section of the game, each with their own achievements for completing all of the ten levels in that section. Each section also introduces a new master, who will imbue the ball with a unique ability when it hits a green peg or block, changing the gameplay in different ways, and allowing players to adapt to different level layouts. During this time you will gain progress toward the peg/block destruction achievements: "Every day I'm Pegglin'", "Orange Crusher", and "I'd Hit That". You will need to go somewhat out of your way to complete achievements such as Baller, which requires you to complete a level with at least 12 balls left, which works with "Superior Shot", or earning 3 free balls in one shot, and "Stylin'", for getting 75,000 styleshot points in a shot. You will also need to completely clear a level of all pegs for "Ultra Extreme Fever" (which you will need to do a total of 60 times for "All the Cheevos!" anyway), and clear all pegs in a level, by hitting the last non-orange block after hitting the last orange peg for"Coolest Clear". During this time you can also work toward getting an ace score for "Ace'd!", although you only really need to focus on completing the levels at this point.
Again, you will have six completion achievements for completing all ten trials in each of the six sections of the game. Trials become accessible after completing the section they are found in (ex. Complete Peggle Institute to unlock the Peggle Institute trials). Trials require players to complete levels in certain ways, or to meet certain requirements such as reaching 150k score with one ball, or completing a level without the aim assist. While most of the secondary achievements are not unlockable in the trials (Coolest Clear in particular), you can still gain progress toward the peg destruction achievements, and also gain some very useful practice for the Secondary Objectives in the main missions.
Secondary Objectives/Clean Up:
To complete the Secondary Objectives - three per main level - you will basically need to do Ultra Extreme Fever (clear all pegs in a level) 60 times, reach a certain ace score 60 times, and meet a varying third secondary objective in each of the levels. The objectives can be completed over the course of several attempts, as long as you finish the entire objective in one run (ex. when asked to perform 5 of one skill shot in a level, all 5 must be done in the same attempt of the level), and even count as completed if you do not beat the level. While it is a good idea to do these while you play through the game, chances are you will want to just complete the levels the first time around, as many of the Secondary Objectives can require considerable extra work and time, however completion of all of the Secondary Objectives is required for the achievement which is perfectly labeled; "All the Cheevos!"
