Daylight Serum

Resident Evil Outbreak- ASI could not beat this part a year or so ago. But I am trying again now.

I told you before I am pretty sure.But this time it is a bit different. I have found the p- base, the t- poison, and the v- blood. The incubator will not accept them and thare is a lokced door in the lab room on the third floor. Do I have to get it open some how iin order for the machine to operate? What do I do?

Some :hint: s would be nice.
