Light No Fire is the No Man's Sky devs blurring the lines between Valheim, Death Stranding, and the open adventure of Lord of the Rings

Seven years after the launch of No Man's Sky, Hello Games is finally looking towards a new horizon. The developer appeared at The Game Awards 2023 to showcase Light No Fire – a brand-new co-op adventure that looks like a daring cross between Valheim and Death Stranding, routed through an expansive fantasy world akin to Pandora or Middle-earth. 

Where No Man's Sky sought to procedurally generate an entire universe, allowing players the opportunity to freely travel between solar systems, as well as name planets, creatures, and locations as they discover them, Light No Fire is taking aim at something more self-contained but no less ambitious. Hello Games is procedurally-generating a single planet to scale – think of how large the Earth is, home to 7.8 billion people and hundreds upon hundreds of millions of square miles of explorable space, and that will effectively be the playground here. 

A survival-crafting game at heart, you'll be able to team up with friends and other players to explore and settle the wilderness. Think of the scenes in The Lord of the Rings where The Fellowship is running across rolling, open expanses – that's the sort of vibe which Hello Games is hoping to cultivate. Your crew may decide to scale a mountain that dwarfs Mount Everest on foot, an act that won't be achievable in a single sitting. Once you reach the summit, you'll be able to see for miles in all directions, pinpoints for where your adventure may go next. Or perhaps you'll build a little homestead, something which other players can discover and use in the future.

This sense of freedom runs through the entire game, where Hello Games wants to induce a sense of gradual exploration as you run the wilds, travel deep underwater, across oceans
