A new achievements listing suggests Crysis 3 is suiting up for multiplayer DLC. Posted on the typically reliable Xbox 360 Achievements, the listing indicates a 250G pack featuring four maps called Creek, Crossing, Ascent, and Coastline, and two modes called Frenzy and Team Possession. The mention of a flag points to Team Possession being a CTF variant.
The DLC apparently also has a new weapon: the boat oar. We mainly wanted to mention it because the associated achievement is called 'Totally Oarsome.'
EA hasn't announced any upcoming DLC for Crysis 3, although developer Crytek previously indicated it had "big plans" for post-launch content. We've reached out to EA for more info.
