Force field generator
A deployable electromagnetic shield that protects against ballistic and energy weapon fire, and which also inhibit the movement of personnel (Lone Wanderer and aliens alike).
Aliens will use the device intelligently, firing at the Lone Wanderer, then moving behind the shield to reload before re-engaging.
It can be deactivated by destroying the projection unit behind the shield by weapon fire or explosives. It will then explode with an effect similar to a plasma grenade.
