For better or worse, Assassin's Creed: Origins is an RPG now, so reckons Tom after going hands-on with Ubisoft's latest sandswept sandbox this week. Due on October 27, the developer has now revealed the minimum and recommended system requirements you'll want to ascertain before descending into the desert. 

As outlined in this blog post, Ubi suggests Origins' minimum specs align with 2015's Assassin's Creed Syndicate, and that those players should expect to run the game at 720p and 30 fps by way of its auto-detect presets.
