XCOM: Enemy Within – Commander Edition – a standalone pack that expands
the XCOM: Enemy Unknown experience featuring the new XCOM: Enemy Within content
and the add-on content that was previously released for XCOM: Enemy Unknown,
including the Elite Soldier Pack and Slingshot Content Pack.
XCOM: Enemy Within takes the experience from XCOM: Enemy Unknown and adds an
array of new abilities, upgrades, and weapons to combat new enemy threats. The
expansion also provides players with all-new maps, tactical and strategic
gameplay, and multiplayer content. Fans will experience an additional three to
four playthroughs on average before encountering all of the new material
included in XCOM: Enemy Within.
