Stalker 2 studio GSC Game World has joined with Ukrainian charity United24 on a new fundraising initiative that aims to raise $100,000 to help fund efforts to remove mines and other explosive devices from the real-world Chornobyl Exclusion Zone.

The Zone—the real one—was established in 1986 following the disaster at the Chornobyl Nuclear Power Plant. It's not quite as fanciful as the videogame counterpart but it is hazardous, and public access is restricted; as one of the most radioactively contaminated regions on the planet, it's also of considerable scientific interest.
