The developers of Prime World recently posted an update saying the closed beta weekends had come to an end and an open date would come soon. That start is now pegged for next Friday, kicking off a weekend of open access for the North American version of the game. Prime World will head into open beta on July 26th, according to an announcement from Nival.
Prime World is quite open, blending a traditional RTS building and resource and production mechanics with an RPG-like crafting and customization system, along with MOBA-inspired gameplay modes. There are also co-op and PvP centered modes, many characters to choose from, including a selection of skins and custom items, in the free to play game.
