Defusing the bomb
When you are defusing the bomb, take your time. After she tells you to pull out the triggers, you can forget all about the water. Now all you have to do is follow the wires coming out of the box that show you the temperature. After that, you must take your time. You have to cut red wires and if you touch the white you will lose. Once you cut all the red wires, you get the operation successful message.
CPR
When giving CPR, putting antibiotic gel on the blue bar before you begin pumping decreases the time the patient spends flatlining by a lot.
Normal and mutated Triti strain of GULT
There are two strains of Triti GUILT. Both have almost the same way to cure it. For the normal type; simply use the healing touch then take out all the thorns. Then, scalpel as much as you can and remove the pieces. If you are fast, you can remove all the triangles in one shot. If any thorns remain, more triangles will appear. You will encounter the non-mutated version of this GULIT once. The mutated form is the same, except when you pull the thorns out they might release white gas. If they release gas, then you must use the drain. Because of the gas you will have to remove the Triti slower than before. Remove all of the thorns like before, and drain any gas that comes out. Then, cut out at least two or three pieces, depending how long it took to take out the thorns. With this form you need the healing touch to slow things down enough to drain gas. If you let gas wander around and do not drain it, it will make more Triti that you have to remove. Note: If you allow the gas to float around or do not remove all the thorns; and your fighting the mutated form of Triti, turn off the game and restart. You must remove all the thorns before you can do anything. If you have a large body of Triti, then you will never be able to remove all the thorns, drain the gas, and cut out the pieces in time to remove them before the thorns grow back.
