An update to Crysis 3's achievement list (spotted by X360A) has uncovered an unannounced DLC pack.

The untitled pack appears to be based around the Nanosuit-shooter's multiplayer, and suggests that a selection of new maps and additional game modes will be included.

The new achievements make mention of four new maps: Ascent, Crossing, Creek and Coastline, as well as two new game modes: Frenzy and Team Possession.

Neither EA or Crytek have yet announced plans to release DLC for Crysis 3.

Crysis 3 was released in February 2013. Sales for the game, however, came in below EA's expectations.
