All surgery requires the set of medical tools in the Operating Theatre, along with a table (a surgical table gives no negative results). For the most part, only medical doctors and the Chief Medical Officer can perform advanced surgery.
For every step there are ghetto analogues. Using them lowes chances of performing a step correctly, wounding your patient. Hover your cursor over the item's name to see the chances.
