Hell:

Hell is a callout for a lower, dangerous position or area on a map, usually a dip, pit, or spot below the main line of sight.

In Counter-Strike 2, players use Hell to describe a place that is hard to see from standard angles but can still control a route, punish rotations, or act as an off-angle for an ambush. The exact location depends on the map, so the term matters most as shared team language: it helps players give fast positional information without naming the full site or route. A common example is calling an enemy “in Hell” when they are tucked below a platform or ledge and can peek up unexpectedly into the site or choke point.
