Create an image capturing the intense gameplay of a fictional sci-fi first-person shooter game called 'Galactic Vanguard.' The scene shows a high-energy combat sequence where the player character, a heavily armored futuristic soldier, is engaged in a firefight against alien enemies in a sprawling, neon-lit cityscape on a distant planet. The player is mid-action, firing an energy weapon with bright plasma bolts illuminating the dark, rain-soaked environment. The heads-up display (HUD) is visible, showing the player's health bar, ammo count, minimap, and objective marker. In the distance, a massive alien warship looms in the sky, adding to the sense of scale and danger. The atmosphere is tense and fast-paced, with explosions and environmental destruction occurring all around. The game HUD also includes a mission timer and a squadmate's status indicator, emphasizing the cooperative elements of the game. The overall aesthetic combines cyberpunk elements with advanced alien technology, creating a visually striking and immersive experience.
