    You need 3 people to open the serum lab and it needs to be on the bigger map with 8 tiles.
    The serum lab is always located in the center tile northeast, southeast, northwest or southwest if you're playing on normal mode.

    The 2 connecting terminals are always in the center tile as well. To find them trace the wires from the serum lab back to them.

    Have 1 person at the lab terminal and the other 2 at the connecting terminals press the button at the same time.

    Once it's opened there is one serum available, and another that spawns after 5 mins. After these 2 are used there will be no more serum spawns during the game. You can use the serum on anyone in the game and it will count.

    ZwaveldioxideYou might want to add that this can only be done on the big map.
