  • Sleight and Haste are recommended to save time and catch runners.
  • Check the smaller rooms first since people tend to hide there.

Bio Lab guide

Bio Lab came out on October 15th, 2015, and it is only the second map Zyleak made for Murder Mystery 2. The wiki ranks it among the largest maps in the game, and that size shapes how it plays.

Layout

A giant grey tube dominates the central area. Around it sit an office, a room of bio-tubes, a workshop, two storage rooms and a vent. Most of the building is cramped corridors and long hallways, so a thrown knife is important here.

Hiding spots

The first one the wiki lists is the Evil Lair, a secret area reached through the column in the corner of the containment room; inside, you can sit-jump to get behind a dummy. Other places are behind the boxes in the bio-tube room, behind some bio-tubes, behind the office locker, behind the workshop boxes, in the vents from the workshop and behind boxes in the storage rooms, including the larger one with flashing red lights.

Murderer notes

The wiki calls the thrown knife essential, recommends Sleight and Haste to save time and catch runners, and says to check the smaller rooms first because people tend to hide there.

Trivia about Bio Lab

  • The second map Zyleak made for MM2.
  • In the early disguises-only days, the map dressed players as a business person, a scientist or an HEV-suit character.
  • A tiny hiding spot also exists inside the huge pillar in the main room.
