Before you storm out into the wasteland to begin your valiant efforts to save our world from a tyrannical world government, you need to build your character. And the first thing to do is choose your class. You character class will help to define your role inside and outside of combat. It will also help govern your abilities and define what sort of bonus' you will receive at milestone events.
Below are the available character classes with a brief description to get you started.
Soldiers- The Soldier makes up the backbone of the TS Resistance. They provide an extra boost boost to the Physical Tree.. While also providing a small boost to Arcana, technical and Mental Trees. They are at home in the field working as a team and are the most effective in groups of 3 or more. A single soldier may not pose much of a threat to Government agents but a squad of highly trained improvising soldiers is tough to beat.
Scouts- Since the collapse the Scouts has become a general term for a branch of resistance fighters who prefer speed, agility, and stealth to overt brute Force. They receive extra buffs to the Technical and Physical Trees but no additional bonus'. Scouts work best alone, part of a surgical strike, or as part of a group where they can be protected.
Nurses/Doctors- Like the Scouts the Nurses expanded their ranks to include Doctors. While they lack major Combat applications they make up for it in defensive and healing capabilities. They provide extra bonus' to Mental and Technological Trees. Medical Staff work best in hospitals and offices. However they also make decent field medics.
Squad Leaders- Soldiers who are actual Div leaders may opt out of the standard classes and choose the Squad Leader class. Div leaders Gain a Small Jack of all trades Bonus to all trees. And share that boost with soldiers in their group. They also work best in groups, providing additional abilities. When the div leader is part of the group, the soldiers are more difficult to defeat, are more effective in encounters, and may retreat more easily. And when in a group gains a standard bonus to all trees. However The Squad Leader and group only receive these bonus' when part of a group. Working together is key.
