Metal Gear Solid 5: Ground Zeroes wasn’t designed for first-person perspective, but it works surprisingly well.
The Metal Gear Solid 5: Ground Zeroes footage below was captured using -Pao‘s FPS Mod.
Uploader BenBlatcher comments that the mod isn’t perfect, as picking up items is weird and some weapons look a bit odd. But the experience as a whole seems kind of cool, and requires you to be a little more thoughtful and careful; when you can’t see around corners, you’ll have to pause and listen for potential hazards.
If you have the PC version of Ground Zeroes, you can try this out for yourself via Nexus Mods.
