In anticipation for the new Metro game I am replaying Last Light and I am disappointed that these guys never rented out their custom game engine. It's fuckin brilliant. It's clear that their developers and designers are skilled but the graphics in their engine is so, damn, immersive. Don't just take my word for it. Here are my actually in-game screenshots. These were just random, no effort put in to the captures. Akthough sadly they are keeping their engine proprietary, I am pretty confident the upcoming game is going to be insane. Last Light just oozes with immersion. The graphics, the sound, the gameplay. Just awesome.
