Due to INFINITAS 2020's restructuring of the mission system on July 26th, 2023, much of the outdated information concerning this mode has been removed. Expect this to be updated as more information comes in.

INFINITAS mission

Missions are a feature introduced in beatmania IIDX INFINITAS on April 12th, 2016. The main goal of missions are to obtain BITs, which can be used to unlock song charts. You get 1000 BITs every time you clear a song above ASSIST CLEAR.

In addition, clearing a song for the first time also rewards you with BITs. You get the following amount of BITs depending on the clear status you obtain. Getting a FULL COMBO, for example, will reward you 1100 BITs, plus the 1000 BITs for clearing a song, granting you a total of 2100 BITs.

FULL COMBO: 300 BITs
EX HARD CLEAR: 200 BITs
HARD CLEAR: 200 BITs
CLEAR: 200 BITs
EASY CLEAR: 200 BITs
ASSIST CLEAR/FAILED: none

You can also use INFINITAS tickets to activate BIT BOOST, which for one hour doubles BITs earned from songs, even for first-time plays of songs. (ACHIEVEMENT and missions, listed below, are not affected by this.)

Note that songs played in other modes (championship, CLASS, or RIVAL CHALLENGE) will not reward BITs.
