Energy weapons skill
Energy governs Energy weapons, which the Skills & Upgrades guide describes as most effective against mechs. It singles out the laser pistol as effective against robot-class enemies and moderately effective against most flesh-based creatures.
How it works
The excerpt presents Energy as a weapon path with uses against both mechanical and flesh-based enemies. It does not provide exact damage values, ammunition constraints, or weapon level requirements, so those details cannot be compared from the supplied evidence.
Read the supporting references
Character attributes, technical skills, combat weapon skills, and operating-system upgrades supported by the supplied System Shock 2 reference windows. Guidance explains the referenced mechanics; it is not a tested damage ranking. Check the stated edition and source version before applying a patch-specific detail.
