Lab 77

Lab 77 is a puzzle game in which you play as Specimen S539-77, completing training in 77 modular test chambers under the supervision of the Director. You place versions of yourself to bridge gaps between platforms, collect lab notes and avoid hazards.

Test chambers

Each chamber calls for careful, strategic movement. On hard mode, the number of placements you can make in a level is limited. Lab notes in each chamber reveal lore about Lab 77, the enigmatic Dr. Leitner and the everyday issues faced by the facility’s staff.

Difficulty settings

The game has three difficulty settings. Easy and medium both allow unlimited placements and return you to the previous checkpoint when you die, without losing placements. On hard, placements are limited and are lost when you die; you return to the level’s starting checkpoint.
