30a37a	1	--- Forcefield generator.
S	2	-- @author ShadowNinja
ee0765	3	--
S	4	-- Forcefields are powerful barriers but they consume huge amounts of power.
30a37a	5	-- The forcefield Generator is an HV machine.
ee0765	6
S	7	-- How expensive is the generator?
	8	-- Leaves room for upgrades lowering the power drain?
