-- Decrease accuracy of HHG/Nuke by 5%
UPDATE weapon_type SET accuracy = 30 WHERE weapon_name = 'Nuke';
UPDATE weapon_type SET accuracy = 30 WHERE weapon_name = 'Holy Hand Grenade';

Decrease Nuke/HHG accuracy from 35% -> 30%
Decrease Nuke/HHG accuracy from 35% -> 30%

This change brings these weapons more in line with the expected power
level scaling. Efficiency should decrease with increasing power level,
and this trend is consistent until power level 5, which had a higher
efficiency than power level 4. Now, the power level 5 weapons are just
slightly below the power level 4 weapons in terms of efficiency.

Note that the PPL remains unchanged in an effort to encourage its use,
since the Nuke/HHG are more effective weapons in general.
