Note: The method used to slow down the song may cause it to sound muddy or robotic.
The Half Time mod is a game modifier that decreases the overall beatmap's speed (BPM) to 75% of the original, increases the length of the song by 33%, and decreases the approach rate (AR), overall difficulty (OD), and health (HP) by a small amount.
In osu!taiko, the slowed song and BPM causes the notes to become very dense due to the decrease in AR. However, due to the way dendens are calculated in osu!taiko, they now take more hits to clear and cause them to award a higher total value than without the mod because denden hits are not affected by the score multiplier.
As a result, using the Half Time mod will lead to an increase in maximum possible score for maps with very low combos and many long dendens. This effect will be even more significant when Hard Rock is turned on simultaneously.
In osu!catch, the BPM is lowered by the same factor as in other modes. Though it also decreases the player character's speed so normal fruits without any mods may turn into hyperdash fruits.
In addition to this, the leniency for hyperdashes is increased, which makes it much more difficult to stop underneath the next fruit when performing a hyperdash.
Objectsvalues will be colored in a light blue with the new values. (Pictured below.)
Objectsvalue will still be colored light blue even though no change in value is actually made.
HPvalues will have a superscript triangle next to their values that indicates a small decrease in their values (pictured below).
