A trilogy of games has been released, each continuing the previous game's story in chronological order. The Mass Effect series combines action role-playing game elements, with the main series games being in third-person perspective. The protagonist can use two AI-controlled squad members in battle, which usually consist of members he or she has recruited from various places and for various reasons, and taken onto the SSV Normandy, Shepard's stealth-recon starship. The player could make prospective decisions depending upon the situation.  At these times, the player has multiple sets of dialogue choices with which to respond to NPCs, separated by tone.  Starting from Mass Effect 2, the player can interrupt cut-scenes calmly or aggressively. The games often have various mini-games in them as well, such as drinking, dancing and romancing characters.
