Aside from being either ground- or space-based, adventure zones vary substantially in their look and feel, with some being more story-driven and less action-heavy (e.g., New Romulus), and some focused on faster-paced combat (e.g., the Tholian Incursion).
Aggro Aggro is a jargon word in MMORPGs, probably originally derived from the English words "aggravation" or "aggression". Aggro denotes the aggressive interests of a monster/NPC. To draw aggro, is to draw the fire of an enemy towards you.
Area of Effect (AoE) Describes a skill or attack that impacts not a specific target, but an area of the map (impacting anything within that area).

Bridge officer (Boff) A commissioned member of the player's bridge crew, which are listed on the left of the Character Status window. While merely serving as pools for abilities in space combat, up to four BOffs can fully join a player's away team in ground combat, offering both abilities as well as firepower.
