Silverlode Interactive announces public alpha testing of Warspire will begin tomorrow, offering invitees the chance to experience this fantasy-themed "collectible" real-time strategy game that is also known as Heroes of Warspire (we're told the title is not yet finalized). The Windows/OS X Linux alpha testing will accept a limited number of players "for server stress testing and game balancing." Here's word on the game:

Warspire is a persistent real-time-strategy title set in the rich fantasy world of the popular MMORTS, SAGA. Players battle online with armies amassed through collectible gameplay. The game is free to play, thanks to this unique collectible dynamic. In lieu of subscription fees, users can enhance their armies by purchasing additional troops. This allows players to customize their forces for endless strategic possibilities. The game also features special faction-specific hero units which have special abilities, level up, and maintain their progress between matches.
