Silverlode Interactive announces Warspire, a "collectible" real-time strategy game follow up to SAGA using units and heroes from all six factions in their MMORTS game. The game is in the works for Windows, Linux, and OS X, and the plan is to launch invitation-only alpha testing this autumn. The game will be free-to-play, featuring microtransactions that will offer gameplay advantages. Here's word:

“With SAGA, the focus is on nation-building and completing quests,” stated Silverlode president Jason Faller. “We wanted the follow-up to be centered on players competing against one another in an intense strategy setting while maintaining the persistency that made SAGA such an innovative game.”

In keeping with this persistency theme, players can select heroes for their army which can level up, gaining greater power and new abilities. This progress is maintained from match to match. In addition, players can purchase new troops with in-game or real life currency to bolster the forces of their armies. This dynamic will allow Warspire to be released free to play.
