ENFILADE

ENFILADE is a siege game about trench geometry. A bastioned star fort commands the top of the map and every foot of open ground before it. You direct the besiegers: open saps from the first parallel, push approach trenches to the foot of the wall, and take the place by breach and assault.

One rule shapes every trench. While you aim a cut, the map draws its full line. If that line touches the rampart, the guns on that face can see straight down the trench, and they rake it end to end with bounding ricochet shot while your men work in it. A pale line is covered. A red line ends on a gun. Zigzag legs flatten as you close with the wall, flank approaches clear the works where a straight push cannot, and every gun you dismount opens a steeper safe line through that face.

Wide cross trenches are parallels. They host batteries, which stay masked until they open fire, and pickets, which stand off the night sorties that come out of the gate after an unguarded sap head. Saps run faster in the dark and the guns fire slower, but the garrison moves at night. Get a battery within musket shot of the curtain and it opens a breach. The assault costs men for every gun still firing, so a cheap storm is earned earlier, in the counter-battery duel. Each front taken leads to a harder one on the same campaign score, with a ravelin before the curtain from the second front on.
