4A Games, the studio behind the Metro series, has shared a few details on its next (still unannounced) game, and according to studio CTO Oles Shishkovstov, the title will be more open than its prior work.
"For the game we are working on now, our designers have shifted to a more sand-box-style experience – less linear but still hugely story-driven," he told Eurogamer. "I will not go into details, but it requires some work from programmers as well.
"Also, we are improving graphics in very different aspects, like recently we did a physically-based global ambient occlusion (instead of local, like SSAO). I will not talk about PBR (physically-based rendering) here, because here we are at the stage when artists are still adapting their mentality to it."
There's no word on whether this new project is another entry in the Metro series or something else entirely. I guess we'll just have to play Metro Redux in the meantime while we wait for more info from the studio.
