Wikipedia said:After the credits, an audio transmission is heard between two people, an unknown subordinate and his ranking superior (known only as "the Overseer" from one of the text logs that can be collected during the course of the game). The subordinate relays that Titan Station (which was Marker Site 12) and the Marker have been destroyed. The Overseer replies that the other sites will then have to “pick up the pieces”.

After the credits finished? I just got the 'you have unlocked xxxx mode' etc.Pretty sure I heard that message on the PC version.
