XCOM: The Board Game – Evolution 2016

Description from the publisher:

Hello, Commander. The war continues – at great cost. We now believe another force is at work against us. If not dealt with swiftly, it could destroy us…

XCOM: Evolution is an expansion for XCOM: The Board Game that complicates your war effort with new missions, enemies, and invasion plans, as well as mechanics that make your struggles more dangerous than ever. As the alien forces spread and peril increases, the sinister humans of the EXALT seek to take advantage of the chaos to infiltrate and destroy XCOM from within. Their treachery leads to new challenges, and you'll face new crises, you'll find your work subverted, and you'll have to deal with new threats to the very resources you need to win the war.

Fortunately, your team has also made some advances since the war began. The discovery of the mysterious alien substance known as Meld promises to unlock some astonishing breakthroughs in the field of biomechanics. And XCOM: Evolution allows you to pursue some of these advances, potentially bringing formidable new weaponry to the field in the form of MEC Troopers!
