Tribes Aerial Assault is a first-person shooter game with an emphasis on mobility. There are many game types in the single-player campaign and multi-player, including capture the flag, capture and hold, hunter, team deathmatch, and deathmatch. Campaign usually consists of some mixture of these game types. In all games but hunters and deathmatch, there are team and player points. Depending on the game style, team and player points can reflect two completely different things. Player points are usually earned through an individual player's accomplishments that help the team as a whole. Player points are earned by setting and deploying equipment, repairing friendly assets, destroying enemy assets, defending friendly assets, and completing objectives of the game.
Capture The Flag: Both teams have a flag, and the objective is to capture the other teams flag. The "runner" is unencumbered by the flag, that is; he/she can still use weapons and grenades freely and without debilitation. After either team has captured the flag 8 times, or the time limit runs out, the game is over and the team with the most points wins. In CTF, team points reflect how many times a team has captured, or attempted to capture the flag. Trying to capture the flag, but dying before reaching the base, gives the player's team one point. Successfully getting the enemy flag to one's own base rewards the player team a hundred points.
Capture and hold: This is an asset-guarding game. Usually there are four buildings or bases scattered over the whole map. Inside each of these is a switch. The objective is to touch the switch in any building and try to prevent the enemy team from doing the same for as long as possible. For every second that a base is held, that team gets one point. When the time runs out, the team with the most team points wins.
Hunter: A survival-based game. The objective is to kill as many people as possible and collect the flags that they drop, and then try to bring those flags back to a central "nexus" for points. There are no teams in Hunter, so everyone is an enemy. If someone drops more than five flags, everyone in the game is alerted as to who has the flags and who dropped them.
Team Deathmatch: Two teams duke it out until time runs out. 1 kill = 1 point. The team with the most points when time runs out wins.
Deathmatch: No teams, few rules, kill or be killed. The person with the most points at time-out wins.
Like most first-person shooters, Tribes Aerial Assault has a Heads Up Display. The HUD consists of a crosshair, health, energy reserve, grenades and grenade type, pack type, armor heat, lock-on detection, and vehicle condition. The HUD also has target identification, that is, a red arrow over the target is an enemy, a green arrow is a friend. An unusual feature of Tribes Aerial Assault is the jetpack feature. The jetpack runs on armor energy and allows players to fly for short to medium distances.

Ransom through missions to fight off the BioDerm horde and keep control of tribal space.
