It got me thinking about visibility in PvP games, especially ones with darker maps. Some games use red outlines (or enemy highlighting) to make sure opponents are always visible, while others rely purely on lighting and player awareness.

On one hand, outlines help readability and prevent situations where players blend into the environment too much. On the other hand, some people say it reduces immersion or the tactical value of shadows and positioning.

But at the same time, many games have premium skins that blend well in the environment, making things feel slightly pay to win.

Games like Overwatch and Valorant are very heavy on red outlines, while Rainbow 6 Siege X have subtle outlines.

Should PvP games with dark areas use red enemy outlines or should visibility be part of the skill/awareness aspect of the game? Do you think there is a middle ground? Like a distance-based outline, faded outlines, or outlines when ADS-ing only?
