Trine 2

Trine 2 is a puzzle-platform game, requiring the player to use the skills of the three characters, Amadeus the wizard, Zoya the thief, and Pontius the knight, to navigate each game level. As with the first game, the mystical "Trine" has bound the three characters together into one common entity, and thus the player controls only one character which can be switched to the other two at any time. Each of the characters has unique abilities: Amadeus can use magic to grab onto certain objects in the game world, and create boxes and planks to be used to get around; Zoya can strike at objects with her arrows, and grapple onto certain surfaces; and Pontius is strong in combat against foes, can bash apart walls, and deflect projectiles with his shield. A combination of these elements is necessary to complete each stage in the game's world.

Characters have individual life meters, and if one character's meter depletes, that character cannot be used until the next checkpoint is reached. If all three characters lose their life meter, the player must start back at the last checkpoint. Throughout the game world are special magical vials, and for every fifty of these collected, the player receives a skill point, which can be used to gain abilities through a skill tree for each character. These skill points can be used collectively for each of the three characters, and can be traded between them.

Trine 2 takes place several years after the events of the first game. The three heroes, Amadeus the wizard, Pontius the knight, and Zoya the thief, are summoned by the magical artifact known as the Trine to embark on a new adventure. Their journey begins when they encounter a mysterious light that leads them into an enchanted forest. They soon find out that a curse has fallen upon the kingdom, and they must help Princess Rosabel, who is desperate to save her sister Isabel and restore balance to the realm.

As they venture deeper into the forest, they uncover a twisted tale of sibling rivalry between the two princesses. Rosabel, consumed by jealousy of Isabel's magical powers, imprisoned her sister in an enchanted tree, causing the land to fall into chaos. The heroes eventually confront Rosabel, only to discover that Isabel has been held captive by her sister for years, causing the forest's overgrowth and allowing goblins to invade the kingdom. After defeating Rosabel, Isabel awakens and, despite the bitterness between them, dives into the waters to save her sister.

The Humble Frozenbyte Bundle, one of the Humble Bundles, started on April 12, 2011, and featured five games from Frozenbyte, including the original Trine, as well as the games Shadowgrounds and Shadowgrounds: Survivor. It also contained an executable version along with source code for an unfinished game, Jack Claw, and a pre-order for their upcoming game, Splot. By April 22, 2011, the Humble Frozenbyte Bundle had surpassed $700,000. Most of the money generated by the sale went to finishing the development of Trine 2 after it was suggested by lead developer, Mike Donovan, that a sequel be made.

The Linux version was delayed from the rest to allow for additional development; it was the first Frozenbyte title ported to Linux in-house, with their other games having previously been ported instead by Alternative Games. Jukka Kokkonen, Frozenbyte's Senior Programmer, revealed that the actual porting was actually "easier than expected", although he did comment that they had some trouble with testing. The port was released as a beta in late March, and is to be released on services including Desura and Gameolith. Kokkonen stated that he hopes that Trine 2 "shows that Linux can provide a proper gaming experience" and that they are "very excited to see how Linux users react to the game.”

Trine 2 received largely positive reviews, earning a score of 9/10 by IGN, and 84/100 for the Windows and Wii U versions on Metacritic, as well as a score of 85/100 for the game's release on the PlayStation 3 and Xbox 360.

By October 2014, Frozenbyte announced that the Trine series had sold over seven million copies worldwide.
