Mass Effect - Rebirth
Special Moves are customized game mechanics that your character either gets for free under certain circumstances or are rare enough that they’re not available for general purchase.
Every character starts with one free Special Move assigned by the GM that reflects their motivation, background, or personality. This starting move will typically be slightly more powerful than the usual moves, and will be unique to your character.
Other Special Moves
There are, of course, other instances when the GM may reward you (or inflict upon you) a Special Move or he may make it available to purchase with the “invent your own move, subject to GM approval, or +1 Move from any list” Advance. Special moves are not always good for you, and some may reflect powerful specialized training or some form of plot bad-candy.
