Grimlore Games and THQ Nordic have announced a new standalone expansion to their fantasy RTS/RPG hybrid, Spellforce 3.

Spellforce 3: Soul Harvest adds two new playable races, the Dwarves and Dark Elves, and a 20-hour campaign that focuses on a war between the two factions. You can check out the trailer above.

The expansion also adds tons of new content for the existing races, including new skill trees, flying units, and a new sector-based approach to the game’s resource mechanics.

Here’s a rundown of the game:

Three years after the Purity Wars, Nortander is on the cusp of a new era.

However, things aren’t as peaceful as they seem – when the Queen calls you, a disgraced General, back to your homeland, you’re plunged in a war on many fronts: While a hatemonger threatens to tear apart the Dwarven realm, an enigmatic cult of Dark Elves harvests the souls of people for reasons unknown.

Gather your allies and prevent a catastrophe!
