draft: System Shock 2 Apollo H4 Laser Pistol run

This is my unfinished guide about a System Shock 2 Apollo H4 Laser Pistol run, the weapon looking like

After activating the Quantum Bio-Reconstruction Machine of a section, the first thing a player should do IMO is to locate an activated Surgical Unit if there's one (in that section), which can be distinguished by having a Surgical Unit Activation Key inserted into it; there's often an activated one, and if one find a key, I suggest to pick it up and keep it in case in an isolated section [spoiler, select to see](which will happen) there's not an activated one. The surgical unit will fill the health and to not have to return to it often, and to save nanites, one should improve Endurance as one of the first upgrade, using Cybernetic Modules in an Upgrade Unit.

Ranged non-psionic weapons degrade with use thus maintaining one is important. A player can do so by using a Disposable Maintenance Tool and having a minimum of 1 Maintenance; the former being limited, I strongly advise to upgrade the skill before starting to use it, advice which at the time of writing this is shared on the tool page in its section Strategic Analysis as

Getting a moderate maintenance skill level (3-4) before starting to use maintenance tools is often preferable. This eliminates high consumption of the tools early in the game

and in that spirit one could use damaged weapons in increasing degree of damage (most used 1st), advice which is partly shared in the same section as

Early in the game, it can be preferable to just swap weapons in poor condition for ones with better condition.

draft

One might consider to first get Agility to 3 and Energy Weapons to 4 and  to use a Laser Rapier, if melee is desired, perhaps as a backup.
melee effectiveness is proportional to strength, and a good advantage to a pure Laser Pistol run is to have more in inventory.

harvesting Disposable Maintenance Tools on Cyborg Midwife and Maintenance Robot; the 2 prevalent on the Hydroponics Deck, and is easy to do so after getting an armor, decent strength & endurance, and a Laser Rapier.

Modifications
20 nanites  initial difficulty 100%  Upgrade 1 - Increases storage capacity by 50%, which is counting Maintenance bonus and increases damage by 10%.
20 nanites  initial difficulty 120%  Upgrade 2 - Decreases energy consumption by 33% and increases damage to a total of 25%.
