Activate a Mechashark X-Steam Controller and use the Mechashark X-Steam to slay The Hammer.
Combining the remains of the Mechachicken with these shark parts, we've assembled the greatest fighting submersible of all time: the Mechashark X-Steam!
Hobart and I want you to pilot it, <name>. Go west to the water and activate the Mechashark X-Steam Controller.
You must kill The Hammer if we're to have any hope of exploiting the natural resources of the Dire Strait to their fullest extent. It's for the good of the cartel!
