The introduction of a grappler gun adds another aspect to movement in the game. This is the first and only game in the Tribes franchise to include such a mechanic.
Single-player
The single player campaign follows five playable characters (Victoria, Daniel, Julia, Mercury, and Jericho) whom the player navigates through 18 missions. The missions are played in achronological order, set either in "The Past" (Victoria, Daniel, Julia, Mercury) or in "The Present" (Julia, Jericho, Mercury), with the former detailing the story of Julia's birth and childhood and the latter describing her search for vengeance upon the Tribals and later, for her own psychological identity.
Multiplayer
The multiplayer mode offers five different default game types and a diversity of map locations. Players are ranked during matches by points they acquire through the match. You can get offensive (killing an opponent, capturing a flag, or destroying enemy equipment), defensive (returning a flag, repairing your equipment, or killing an enemy flag carrier), or by style points (hit a head shot with a sniper rifle, or hitting someone in mid-air with a spinfusor disk).
Arena is a 'Team Free for All' in which two teams fight for up to 9 rounds. There is no respawn, so once a player dies, they must wait for the next round before they can play again. Whichever team has more rounds won at the end of a match wins. This game type is inherited from earlier Tribes games.
Ball is a game type where two teams play against each other with a goal for each team. There is a single ball located somewhere on the map, usually in the middle. The objective is to get the ball and throw it into the enemy’s goal. Whichever team has the most points at the end wins. This game is original to Tribes: Vengeance, but also resembles Unreal Tournament 2003 and Unreal Tournament 2004's Bombing Run game.
In Fuel, both teams have a fuel depot at their base. There is one neutral fuel depot which the players can collect fuel from, as well as a depot for each team. Players may stand within these to gradually steal fuel or, if it is their own team's, to deposit fuel. The less fuel in the depot, the slower it takes to collect it. As well as the depots, players can collect fuel cells from the ground that may have originally spawned there randomly on the game's start, or have been dropped upon a player's death. The maximum amount of fuel a character can carry is 15, and each fuel cell contains a specific amount of fuel. Whenever a player dies, their team's fuel depot loses one unit of fuel. Whichever team fills their depot first is the winner. This game type is original to Tribes: Vengeance
Rabbit is the only 'Free for All' game mode in Tribes: Vengeance. In this, there are no teams, but a single flag on the map somewhere, usually in the middle of the map. The objective for every player is to retrieve the flag and run. Whenever a player retrieves the flag, every other player will be alerted, and whoever has the flag will be marked as their enemy. Points are gained by holding on to the flag as long as possible and killing the other players. Points are lost by killing somebody who does not have the flag. No points are gained by killing the flag carrier. The game is timed, and whoever has the most points at the end is the winner. This game mode is common to all Tribes games, as well as many other games.
Capture the Flag mode is similar to its Tribes equivalent. There are two teams, each with a flag and a flag stand. The objective for each team is to capture the enemy flag and bring it back to their base. However, the team’s flag must be at their flag stand in order for them to capture the enemy’s flag. Points are awarded for every flag capture, and for every flag return. The game can be ended by time running out, or a team capturing the enemy flag until the max amount of captures achieved. If it is ended by time, whichever team had more points wins. Matches can end in the event of a tie.
Plot
Set hundreds of years before the events of Starsiege: Tribes, Vengeance depicts the birth of the growing Tribal War. It focuses on the events surrounding five different characters over the course of two generations and how they each contribute to the developing war. The story ("The Past") begins with a Phoenix sub-clan leader named Daniel abducting the soon to be Queen, Princess Victoria. He takes her to his home world to show her the injustices done to his people and the two eventually fall in love. During this time, a cybrid assassin named Mercury is hired by an unknown contractor to eliminate Daniel, but the contract is canceled moments before the shot is fired. Eventually, Victoria and Daniel try to make amends between the Imperials and the Phoenix, but it all ends disastrously when the Phoenix's enemies, the Blood Eagle tribe, stage a raid on a Phoenix base disguised as Imperial troops. In rage, Daniel kills the Imperial King, Tiberius, whom Victoria avenges by killing Daniel. It turns out that Victoria is pregnant with Daniel's child, who is born female and named Julia soon thereafter.
