Bio Laboratory

"The abandoned lab is now operational. Investigate and destroy the lab."

- Stage description

Bio Laboratory (バイオラボラトリー) is Split Mushroom's stage in Mega Man X4. It is an old biological laboratory that has been taken over by plants.

Bio Laboratory Area 1
The first half of the stage is divided in three sections. The first section is a giant spiral staircase with an array of enemies and a teleporter on the end of the section. The second section has a few platforms with death pits at the beginning and some ladders to reach the top. Along the way there's Tentoroids BS which are indestructible and will attempt to crush X/Zero. After reaching the top, the final section of the area has a few platforms and a fight with the Tentoroid sub-boss. After destroying it, one can reach the end of the stage area.

Bio Laboratory Area 2
The second half of the stage is also divided in three sections. The first section is also a giant spiral staircase, however, with more aggressive enemies and a Death Guardian chasing X/Zero from behind. The second section has Tentoroids BS destroying sections of the stage. A Life Up can be seen right away, which can be reachable by using the falling roof of that part of the stage as a platform to reach the top or by using Lightning Web with X / Kuuenbu with Zero. Dashing through the falling platforms is the most recommended approach as one has the risk of getting crushed or falling alongside the platforms. The third section is a giant elevator with a blue variant of Togerics attempting to smash X/Zero with the lenght of their root and firing shots and bombs. After a while, a few platforms will appear, which will crush X/Zero if they are not careful. Split Mushroom is on top of this section.
