The L2 BIO Plant and the L3 BIO Lab are two facilities within the EFI Research Facility, as well as levels in The House of the Dead III. Depending on the player's decisions, they will journey through either facility.
Upon reaching the Bio Lab (or Bio Plant), G asks Lisa Rogan if she is getting along with her father. Lisa believes that his father puts work ahead of his family and she barely has any moments of him spending time with her and her mother. G remarks this as harsh, as Lisa replies "What do you expect?" because he always makes the family worry, giving Lisa a desire to "slap him upside the head, for Mom".
They then fight off mutants along the way, even being greeted by mutant plant tentacles. Lisa remarks that the facility is more of a jungle (Bio Lab) or the inside of a giant plant (Bio Plant) than a laboratory, as they continue fighting mutants along the way, before meeting up with the source of the tentacles, a mutant tree codenamed Sun.
They manage to defeat Sun as they escape from the facility, with Lisa remarking sarcastically that she "never was any good at gardening". They then find a door blocked by tree barks, and as G shoots the barks, the door opens as they make their escape through the other side of the facility in one piece.
G asks Lisa if she is worried about her father, which she brings to mind one quote he once said: "Believe in yourself". Lisa remarks that he keeps saying the same thing over and over and she's fed up with it.
