dungeon crawler video game style, first person perspective, grid based movement, rpg elements in the heart of a dimly lit bunker, a 42 year old calvary officer stands vigilant amidst the ruins of a once futuristic laboratory. cubo futurism style dominates the composition, as fractured planes and geometric shapes converge to create an atmosphere of destructive intensity. the air is thick with the acrid smell of smoke and ozone. the officer's armor, dented and charred from countless battles, seems to absorb the faint light that seeps through the bunker's makeshift windows. his face, weathered by countless years of conflict, is a map of scars and creases, yet his eyes burn with an inner intensity, fueled by the formulas etched on the walls around him. the formulas themselves appear as jagged, neon lit hieroglyphs, pulsing with an otherworldly energy. they writhe across the walls like living serpents, as if attempting to break free from their geometric constraints. the officer's hand rests on the hilt of his sword, a gesture both defensive and contemplative. in the background, the ruins of machinery hum softly, a distant reminder of the catastrophic event that brought humanity to its knees. amidst this desolate landscape, the calvary officer stands as a beacon of determination, his presence a testament to the indomitable will to survive in a world reduced to rubble.
