Amazon is kicking off Cyber Monday with deals on Tekken Tag Tournament 2, Devil May Cry HD Collection, and XCOM: Enemy Unknown.

Gettysburg and Civilization designer, Sid Meier, is in Firaxis Games’ XCOM: Enemy Unknown.

To be more specific, the game will switch between the two modes.

XCOM: Enemy Unknown is a turn-based strategy game that Firaxis say will remain true to the original X-COM.
