Hitting the 'F7' key can toggle environmental effects. Within the game, players can toggle between 4K resolution and the original's graphics settings for the visual effects by hitting the 'F5' key. Dialogue and audio are revised, the audio sample rate increased to 44kHz. Classic cinematics are rendered in 1080p, and gameplay will have 4k resolution.
Illustrated segments within missions will vary in depiction, ranging from a wide view of the environment to a close-up of a character's face. The briefings from the original game are retained, but will receive added visual effects. The comics replace segments of the original game where green text was used on a black screen to convey narrative. The campaign is present as well, with comic-style interludes and briefings between and during missions. The game features updated visuals, some polished versions of the old sprites, some built from the ground up based off of the ideas of the original artists and concept art.
