Abh mod/Advanced Shield
The advanced shield generator has a 90 degrees arc of coverage and a shield geometry of a circle with 10-tile unit radius. In comparison the vanilla Shield Generator has a shield geometry of a circle with 7.5-tile unit radius and a power drain of 100 power unit points per second. As such the power drain of the advanced shield is 10/7.5 = 1.3 compared to the vanilla shield which translates to 130 power unit point per second. As an improved shield AmmoDrainPerDamage has been decreased from 0.5 to 0.25. This means its damage load is 1/0.65 ~ 53% less for a limited bombardment and 30% more for a full scale bombardment. With only 7 batteries compared to vanilla's 6 at disposal, the shield will fail (6/1)/(7/1.3)= 1.114 sooner in a comparative setup under the same full scale barrage.
