Tribes: Vengeance is the third game in the Tribes series, and the first to have a significant singleplayer mode. It is a sci-fi shooter with diverse character classes, expansive landscapes which can be traveled by foot, jetpack, or vehicle, and bases and base facilities to defend and/or infiltrate. The plot takes place hundreds of years before the previous Tribes games, and shows the events that take place prior to them through the eyes of six different characters over two generations.
