jweaver64:All of your questions have already been answered. More than once, in fact...
Clockwork Kaz fires itself when it's near an enemy
Get out of your vehicle to use the turrets
The sail won't work if you have wheels
There's nothing wrong with the game, it's just that there are special ways in which those specific parts work.
Actually, they weren't at the time you posted... I figured out the sail thing before checking back with the thread - works like regular motor (LT and RT triggers to move). I thought it was something you had to activate like the weapons.
As far as the turret - mine was high up on the vehicle I was testing things on and I never got the "Y" enter to show up until I climbed up, then it was obvious.
My second question regarding the Clockworks was more along the lines of "How close do you have to be? Do they target the biggest enemy or the closest?" - I guess I wasn't clear about my line of questioning, sorry about that.
Thanks to all in the thread for the help.
