Might & Magic: Clash of Heroes is a puzzle role-playing game in the Might and Magic franchise, developed by Capybara Games and published by Ubisoft Entertainment. It was initially released 2009 for the Nintendo DS. An HD version was developed for the PS3, Xbox 360 and Windows PC, and was released 2011. A version was made for iOS and Android, and was released 2013.
Borrowing elements from the Heroes of Might and Magic franchise, it combines elements of the role-playing, turn-based strategy and puzzle video game genres, allowing players to embark on story-based and optional quests while employing army recruitment and resource management. Each faction has three types of basic troops, and five types of more advanced troops, with players selecting from these to form their individual army compositions.
The player controls individual heroes representative of each faction, each of whom act as avatars in alternating exploration and battle phases, growing in experience and obtaining new abilities as the game progresses.
