Tags
Tags are descriptors that attach to your character for a variety of reasons. Some, like +boosted are situational, granted temporarily due to circumstance. Some, such as +cyberbrain describe some aspect of your morph that is intrinsic to it. Others, such as +pneumatic limbs, are descriptive of some sort of mechanical or cybernetic enhancement. Some tags apply to equipment, such as the +reload tag.
Whatever the source, tags work the same way. They are a mostly descriptive, narrative thing that enables your character to do things they may not be ordinarily able to do, or they create some complication for your character to overcome.
