Overload the generator. Exhaust turbines destroyed: 0/3
This is easily one of the trickiest parts of the mission. The 2 sided, dual level turbines move in opposing directions. If they touch you, you die.
Wait for either of the turbines to go past and then drop down into the opening below you.
Once there, fire at the spinning turbine in the ground just in front of you. It will break and begin to overload the generator.
Head to either the left or right. It is important to wait for a turbine to pass above you. Start running just after that.
This lets you dodge the turbine and have more time before it comes back and a better chance to make it to the next opening.
Slide into the opening where the vulnerable turbine is.
Continue in the same direction to the third and final opening.
Drop in and destroy the last of the exhaust turbines.
With the last exhaust turbine destroyed, stay in the opening until the ones above you stop moving and power down.
