Ubisoft’s AnvilNext engine is the heart and soul of Assassin’s Creed III, powering what is no doubt the most technically advanced and deeply immersive game in the series yet. Dynamic weather across all four seasons. Advanced AI. Expansive battles containing upwards of 2,000 NPCs on screen at once. Naval battles with realistic wind and water simulations that directly influence sea conditions. A thousand new character animations. Retooled combat. Yowsers, what does this game NOT do?
