TENACITY is the second level of BIT.TRIP Runner. It contains eleven stages, eleven Retro Challenges, one boss, and two songs, Tenacity and Conviction.
TENACITY takes place on a mining facility located on some planetoid. It's covered in large amounts of construction equipment, making the place a significant hazard, forcing CommanderVideo to bring his A-Game if he intends to see his quest to its conclusion. It is here that he meets Radbot, and learns about his shield ability, which calls upon the Paddle from BEAT.
This level is preceded by IMPETUS and succeded by TRIUMPH.
