For "ZERO HOUR" and "three-dimensional maps" like R6

ZERO HOUR" feels to me like a new entry in the "Swat" series, knowing that "Swat" is considered the originator of the tactical FPS, and in the 90s it achieved the combination of FPS, tactics and realism. However, the authenticity of "Swat" is reflected in the many non-lethal weapons, "bloodless" is the main gameplay of "Swat", while "ZERO HOUR" is the replacement of this part of the content into the combat content. Even so, ZERO HOUR's combat experience is not comparable to R6's, and not just because of bugs, modeling, feel and other details. Because for "ZERO HOUR", after all, out of the prison test phase, R6 is also gradually get rid of the bugs after the health action.
