Antigrav Struts (SMAC)

Antigrav Struts is a special unit ability in Sid Meier's Alpha Centauri.

Game info[]

Required technology: Graviton Theory
Cost: 1
Description: Give a unit an extra move each turn, and allow all ground units, like Hovertanks, to avoid movement penalties for difficult terrain. Air units with Antigrav Struts gain moves equal to twice their reactor value (so an Antigrav air unit with a Fusion Reactor would gain 4 moves).
