Identification badges, (or I.D. badge for short), are small hand-size cards. In Halo 3: ODST, multiple identification badges can be found, sporting the faces of Bungie employees. They can also be found in the Halo 3 level Floodgate.
Locating the badges
These badges can be found in many places throughout ODST in both firefight and campaign. Such as on the firefight level Security Zone there are two badges that can be located near the spawn point on the table in that room behind you.
