Epic Book Cover Design for 'Zlittya Vsesvitiv' Featuring Iconic Game Heroes

"Design an epic book cover for 'Zlittya Vsesvitiv' ('Merge of Universes'), featuring characters from Overwatch 2, Valorant, Apex Legends, and Rainbow Six Siege. The heroes, in their iconic gear, should stand together in a powerful, action-ready pose. Their futuristic armor, tactical outfits, sleek agents, and rugged survivalist looks should contrast but unite them against an impending threat. In the background, depict a Dark Entity, a mysterious, otherworldly antagonist with glowing eyes and a shadowy, ethereal form. Its tendrils or aura should wrap around the characters, symbolizing the merging of these universes. Use a dark color palette with deep blues, blacks, and neon accents. The title 'Zlittya Vsesvitiv' should be bold and modern, standing out against the dark tones, creating an intense, action-packed atmosphere."
