ISOTX announces that Iron Grip: Marauders is now in open beta, offering the opportunity to go hands-on with this turn-based strategy game that's played in a browser that they've dubbed an SBBG (Strategy Based Browser Game). The free-to-play game uses the Unity engine for a fully 3D experience. The beta is live, but they are still planning improvements. "We still have many ideas for new units and features. Over the next months, we will try to work these out and implement them into the game. So, stay tuned for news updates," says Creative Director Vincent van Geel.
