First-person games place the camera directly behind the character's eyes, so you see the world exactly as they would. This perspective heightens immersion and precise aiming, which is why it dominates shooters and survival experiences. Portal leans on it for spatial puzzles, while Counter-Strike: Global Offensive and Rainbow Six Siege rely on its accuracy for tense gunfights. Expect strong presence, careful navigation, and a viewpoint that makes every corner feel real.
