My best-ever deathmobile (with the Vehicle Additions Pack in place) had 4x laser cannon turrets and 4x pulse laser turrets set to auto. Then it had 3x turbolaser turrets set to manual. With 10 storage batteries, 12 advanced solar panels, and a minireactor for power.
It was game-breaking. Cars blocking the road? Hop on the turbolasers and blast them until there’s nothing left but scrap. All the noise attracts a horde? Who cares, the auto-lasers will cut them all down as soon as they come within range.
God it was great. I need to build another one.
