Energy Pack
 Increases your armor's energy recharge rate. It will allow you to keep recharging energy when hit with an EMP

Repair Pack
 Repair yourself, inventories, generators, deployable's, and other players.

Shield Pack
 Causes damage done to you to be taken away from your armor's energy and not your health. Also does not allow EMPs or poison darts to penetrate the shield. Beware the Railgun.

Sensor Jammer Pack
 Suppresses pulse sensors. Check out the Sensor Network Guide for more information.

Cloaking Pack
 Renders you invisible (to anyone with a 3D card) and suppresses pulse sensors. If detected by motion sensors or enemy players then you will have a red arrow above your head. Although... there is a way around this...

StealthShield Pack
 A Shield Pack and Sensor Jammer Pack hybrid. This shield will not stop EMPs or poison darts.

Cybernetic Laser
 This shoulder mounted laser draws from your armors energy cells to fire a laser blast similar to that of the Laser Rifle, although it is allot less powerful. Using this in conjunction with another sniping weapon is a deadly combination. Its high drain on your energy cells cause them to not recharge for a few seconds. This pack requires a free weapon slot.

Auto-Rocket Cannon
 Upon activation this shoulder mounted launcher shoots a rocket. This allows you to fire off rockets while fighting with another weapon. This can help a Cyborg hold his own on open ground.

Command Laptop
 This pack allows you to control turrets without being at a command station. Also, you can attach this to enemy turrets by touching them. After a few seconds, if you are still alive and the turret is not destroyed, the turret will be reprogrammed, converting it to your team. It takes the Spy longer to take over a turret than the Engineer or Infiltrator.

Demolition Pack
 A portable bomb. Upon deployment you have 20 seconds to run like hell. Also detonates if you commit suicide (ctrl+k).

Ammo Pack
 This pack allows you to carry extra ammo and Repair Kits.

Power Core Pack
 This pack can be used on a station, turret, or sensor to power it when the generators are down. When used on a player it greatly improves their armor's energy recharge rate. This pack can also be used to enhance the energy systems of a teleporter.

Heat Sink
 This pack hides your heat signature from Rocket Turrets, they will no longer fire at you. Also reduces the effect Tractor Turrets and EMPs have on you and makes you unable to catch on fire. The Heat Sink also increases the efficiency of Mercenary Boosters.

Teleport Pack
 When used this pack attempts to find a Teleport Beacon in range. While they do have a short range (~60 meters), if you are close enough you will gain control of the beacon.
