Gung Ho
Snake Eyes
BackBlast
Agent Helix
Shipwreck
Beachhead
Kamakura
Sgt. Flash
COBRA
Storm Shadow

Most of the G.I. JOE contacts are found by simply finding their dog tags hidden throughout levels in the game. However, both Snake Eyes and Sgt. Flash are taken prisoner and must be rescued in bonus missions.
Storm Shadow is obtained by defeating him three times in his secret lairs. The rest of the COBRA characters are received after completing a bonus mission upon beating the game.
Remember that this achievement is for collecting the contact, not purchasing it and being able to use it in the game.
This trophy is confusing. All G.I. Joe contacts actually means All Contacts. You must complete the final bonus mission (unlocked by beating the final story mission) in order to unlock three Cobra characters for purchase. You must also unlock all the G.I. Joe characters for purchase. You do NOT have to purchase all characters for this trophy to unlock. You can find contacts in missions (usually behind ability doors). This trophy will unlock after the Mission Select screen has loaded upon completion of the level/requirements. Here is a list of all the characters you must find:
Duke
Scarlett
Heavy Duty
Ripcord
Gung Ho
Shipwreck
Baroness
Beachhead
Kamakura
SGT. Flash
Snake Eyes
Backblast
Agent Helix
Storm Shadow
Firefly
Destro
