Earlier this year, Metal Gear Solid Delta: Snake Eater was announced as a remake for Xbox Partner Preview. As we see in the trailer, the game uses Unreal Engine – it’s unclear whether it’s Unreal Engine 4 or 5, though – along with some quick snippets of tactical espionage.
The footage shown is definitely gameplay, but it doesn’t appear to be final as it’s referred to as the “first in-engine look.” Furthermore, it’s watermarked with “pre-alpha footage.”
