In Mass Effect 2 for Xbox 360, there is a laundry list of bonus skills you can unlock for use with your main character by completing the loyalty missions of your crew. You can only have one active at a time, but some will come in very handy when you need them.
Once you unlock the bonus skill, you will have to train in it at first, but any new characters you create after it’s unlocked will have it available to choose from automatically.
Armor Piercing Ammo – Complete Archangel’s loyalty mission
Biotic Barrier – Complete Jacob’s loyalty mission
Dominate – During Samara’s loyalty mission, kill her and replace her with Morinth
