In Starsiege: Tribes any armor class could use any Pack. A Pack gave the player a new ability, or could be deployed in the field. The available packs are listed below:
Energy Pack
Increases the recharge rate of the armor power cell. This miniature fusion pack is especially useful when combined with an energy based weapon, like the laser rifle. It is also well suited to aid the lighter armor types in speedy escapes.
Repair Pack
A battlefield repair kit, this pack comes with what is colloquially referred to as
the “repair gun.” Using exotic nanotechnology, it can repair armor, vehicles, and base emplacements such as turrets and generators.
Shield Pack
Requires energy from the armor’s power cell. To activate, press P. The shield pack creates an auxiliary energy shield around the user as long as the power cell has energy. While the pack is operating the shield will absorb some, if not all, damage directed toward the player. The pack can be deactivated by pressing P. It will automatically deactivate once the power cell runs out of energy.
Jammer Pack
Requires energy from the armor’s power cell. To activate, press P. The jammer
pack will make the user and any other players within 20 meters undetectable to enemy pulse sensors. The pack can be deactivated by pressing P. It will deactivate automatically once the power cell runs out.
Ammo Pack
Increases the maximum ammo the armor can hold. This pack does not require any energy from the power cell to operate. If this pack is dropped, all extra ammo beyond what the armor will carry is left in the dropped pack.
