Skills allow for differentiating agents and specializing them in particular fields. Skills have a variety of characteristics. Some improve stats while others grant new abilities. Generally, ability skills have a cost such as consuming Energy or causing an agent to lose movement. Be sure to read each one thoroughly before selecting them. A player can run through the game many times and choose a completely different set of skills to level up. This will dramatically alter the playing experience and players can custom build the agents depending on the player's style.
All skills will cost from one to four Skill Points depending on the skill and its current level. Skills Points are collected by each agent as the agent's level rises (one point per level). Points can be saved until enough are built up to purchase another rank in a specific skill. Agents gain experience for leveling by performing actions, trespassing, and in combat. The actions of one agent will affect the experience gain of the other living agents. Dead agents cannot gain experience.
In Ironman mode, all the skills and experience of an agent are reset upon that agent's death.
