Perfect Dark Zero getting new maps and a bug fix
Map details:
Facility - This dilapidated Soviet installation has been the centre of a firefight and has generally seen better days but should feel strangely familiar
Ruin - A hidden ruin being used by dataDyne in connection to the Graal, older visitors will feel an odd sense of dj vu
Both maps will be available as a free download on Xbox Live Marketplace as Map Pack Two.
In addition, an update will be prompted next time you log into XBL that will will address the Cover Move exploit that had allowed players in multiplayer matches to hide inside of game geometry.
