Sentinels combine biotic and tech abilities. Typically they use biotic abilities and advanced healing skills to defend allies, though they can also disrupt opponents with biotic or Tech attacks. They are more efficient at tech and biotics than other classes, but at the expense of combat. Sentinels can only use light armor, and receive no advanced weapon training.
VanguardsVanguards are biotic warriors. They combine offensive biotic abilities and weapons training to quickly take down opponents, and are especially deadly at short range. They can train with pistols and shotguns, and can learn to wear medium armor.
InfiltratorsInfiltrators combine combat and tech abilities, and specialize in killing or disabling enemies at long range. Infiltrators are trained to use OmniTools, but the focus is on decryption and offensive abilities rather than healing. They can train with pistols or sniper rifles, and can learn to wear medium armor.
AdeptsAdepts are biotic specialists. Starting out equipped with pistols and light armor, the true strength of the adept is through the upgradeable implants that give them their biotic powers. These powers can be used to lift or throw objects, shield the party and disable or destroy enemies.
EngineersEngineers are tech specialists. Using the holographic OmniTool they can decrypt security systems, repair and/or modify technical equipment, disrupt enemy weapons or shields and heal their party. Even though they begin the game with only pistols and the OmniTool, engineers can unlock the ability to wear light armor and to reverse engineer enemy technology. They can also learn to put up protective shields and to heal the party.
SoldiersSoldiers are combat specialists ideal for the front lines of a firefight. Soldiers begin the game trained with skills in both pistols and assault rifles, they have improved health and the ability to wear medium combat armor. As you progress through the game you can unlock assault training, skills with shotguns and sniper rifles, become able to perform first aid on yourself and party members, and wear heavy combat armor.
