Folha de conceito do jogo Rogue Viper

Create a cinematic game concept sheet for an original stealth action game titled "Rogue Viper". Layout: a wide 16:9 production board divided into four labeled panels.

Panel 2 shows enemy enforcer variations in black armor with red visor details, including standing, crouching, and aiming poses. Panel 3 shows a dark alpine black-site research facility environment with cold lighting, industrial walkways, server racks, patrol lights, and stealth mood. Panel 4 shows an action set piece at a collapsed freight depot bridge during sunset, with the protagonist firing pistols, enemies in motion, dust, sparks, helicopters, and cinematic depth. Add a restrained color palette strip at the bottom with matte black, charcoal, gold, gunmetal, deep red, slate gray, and cold white.
