Spectromancer is a computer game developed by Apus Software and Three Donkeys LLC. The game was released in October 2008. The expansion League of Heroes is an upgrade to the game rather than a stand-alone expansion and was released at 2010-03-02.
The game was developed by Magic: The Gathering creator Richard Garfield, Alexey Stankevich (creator of Astral Tournament and Astral Masters) and Skaff Elias. Spectromancer's gameplay revolves around a playing-card dynamic. In the single-player campaign, the player traverses a mythical world collecting various cards to use in duels. There is also an online arena, where a player can duel other players, and a high score list.
Unlike most collectible card games, players do not construct a deck before the game starts. Instead, at the beginning of each duel, each player is randomly given twenty cards, four from each of five elements. (The four classical elements, plus a fifth element of the player's choice.) These cards vary in mana cost and function. Each turn, the player gains one mana in each element, and may play a single card. Playing a card does not cause it to become "used"; there is no concept of a hand or a discard pile. The game ends once one player succeeds in bringing the other player's life total down to 0.
The free trial offers the full single player mode and online mode, except that the player can only play as an Illusionist in the free trial. The full, purchased version offers eight more classes, with their corresponding specialties.
