Vehicle Combat
Success Rate: +5% to hit (only applicable when in a moving vehicle)

This skill helps to negate movement modifiers in vehicle combat. Attacker must possess the corresponding skill for the weapon used. The modifiers only apply to combat scenarios that entail moving vehicles...for example a person standing on the ground may use it to fire upon a moving hovercycle, but not at occupants in a parked ground car --- or a person in an air car may use it to fire at ground targets (stationary or otherwise).

Zero Grav Combat
Success Rate: see below

This military skill allows for improved combat prowess in a zero gravity environment. 0G combat decreases a character's dexterity by half, as well as mandating a RS check after each firing action to maintain (or regain) control. The 0G skill allows a +5/level bonus to the DEX (not to exceed original dexterity where aplicable) and a +2/level bonus to the RS check.

Part 3: Bio-Social Skills

As with the Technical Skills, the Bio-Social Skills also remain the same but the sub-skills are individually increased as the player gains experience. This allows for a more fleshed-out skill, one medic may be more adept at surgery, while another excels at diagnosis and a third can be a disease expert, etc The bio-social skills are still divided into three fields: Environmental, Medical, and Psycho-Social.

A starting character gets the skill at the LVL:1 Buy-In, meaning he/she recieves all the subskills at level one. The LVL:0 Buy-In refers to characters that wish to add a second or third bio-social skill field to their character (such as a medic adding the environmental or psycho-social field). Buying in gives the character all the subskills at zero-level, meaning he/she may use the skills with no bonuses. 

Adding a second or third technical skill field at the LVL:1 Buy-In allows the character to start with the new skill with all subskills at level one. This requires expending one XP (2 for non-BioSocial PSA) per subskill, so to acquire the Medic set it would take 9XP as there are nine separate subskills in that field.

Increasing the individual subskills is explained in the following table:

	PSA XP	non-PSA XP
LVL:0 Buy-In*	3	6
LVL:1 Buy-In	1/subskill	2/subskill
individual LVL:2 skill	0.5	1
individual LVL:3 skill	1	2
individual LVL:4 skill	2	4
individual LVL:5 skill	3	6
individual LVL:6 skill	4	8

* Increasing LVL:0 subskills to LVL:1 can be done at 3 subskills per XP (3 subskills for every 2XP for non-PSA), leftover skills per XP are lost.

New Bio-Social Skills

Bluffing
Success Rate: ¼ (LOG + PER) + 10%/level

Misc. Skills

Vacc Suit
Success Rate: automatic 

Any spacer, upon acquiring one of the various ship skills, is eligible to learn the skill of donning and using a spacesuit. One experience point must be expended and there is no skill level, the success rate is automatic. Time is halved when donning a spacesuit compared to the unskilled, and add a +10% bonus to repair work performed (patches etc). Anyone without a spaceship skill must expend 3XP to acquire the skill.
