Energy Pack:
Enhances your energy systems and doubles your energy supply.

Repair Pack:
Used to repair anything and everything.  Has  a quick repair rate.

Shield Pack:
Once activated it forms a energy shield around the carrier that prevents projectile weapons from doing their normal damage.  

Sensor Jammer Pack:
When on it jams all pulse sensors but has no effect on motion sensor, so beware.

Cloaking Device:
Once activated cloaks the player and their weapons.  Blocks all sensors except motion.

Ammo Pack:
Very simple, it allows the player to carry more ammo for each weapon they are carrying, to include mines and grenades.

Stinger Cannons:
This is a twin shoulder mounted rocket firing cannon.  It is energy, but has a quick reload rate.  The missile do minimal damage,  and are meant more for annoyance.  They fire straight unlike the heat seeking missiles

Hell Fire Pack:
This is a shoulder mount weapon that fires a vulcan round.  It doesn't have ammo, and zaps your system energy quickly.  Good for those incoming Devestators that are attacking your base.

Demolition Pack:
This is a toned version of the Nuke, you could call it the sister Bomb.  It has a 5 second delay for arming and must be set off using the same button you deployed it with.

Nuke Bomb:
The name should say all, but just in case, if you didn't get it, this bomb will take out everything and anyone in its blast path, to include players on either team.  Once deployed it will arm itself in 10 seconds.  Use the same deploy button to detonate it.

Heat Sheild:
This pack will mask your heat signature while jetting around the map. This helps you avoid those pesky little heat seaking missiles.

Absorber Pack:
This is a useful to "absorb" energy attacks from energy projectiles. When the pack is active, you can not be harmed from a attack is pure energy.

Regeneration Pack:
While wearing this pack you will automatically be repaired when you have received damage.

Ripcord Pack:
This is a personal teleporation system. The idea came from Allegiance, when you could "Ripcord" out of danger. You create a ripcord beacon upon activation of the pack, when activated again you return to the ripcord beacon. The range varies from 80 to 100 meters.

Disruptor Pack:
This is a fun pack to wear to mess with the other team. It will mask you as a member of the opposite team and with that you have full access to all of the other teams items. The downside is, you cannot capture the flag while wearing the pack, and the energy drain is quick, so don't expect to play the entire match using this pack.
