Just like its elder siblings, AoE3 has reworked 4K visuals and enhanced audio, and more specifically it has two new civilisations (the Inca and the Swedes) and two new game modes (Historical Battles and The Art of War Challenge Missions).
Microsoft and developer World's Edge are bringing back the third game in the classic Ensemble series, following hot on the heels of Definitive Editions for both Age of Empires I and II. One of the announcements to make it out of Gamescom Opening Night Live this evening was the big reveal of Age of Empires III and the confirmation that the game is heading to PC in October.
