Nothing like Fallout. Mostly linear. There's a tiny bit of exploration in a spot or two but that's it. There are merchants and scavenging for ammo, health kits, weapons, and gas mask filters but no leveling or skill trees.
It's basically a low light corridor shooter. Lots of cinematics, a few quick time events, and auto health regen(with shots for quick health boost during battles). In other words, your average modern FPS with a bit of stealth, some great levels, and awesome graphics.
I might give it a second playthrough, but the fist 3 hours(out of roughly 10-12) are painfully slow 7.8/10
Great topic. Every FPS game I buy, I hope for the reincarnation of Fallout 3. Metro Last Light is a cool game in its own right, but it is like the subway tunnel portions of Fallout 3. I sure hope someone is developing Fallout 4.
