Looking for an opportunity to jump in on the XCOM franchise? Amazon is currently offering the PC versions of Firaxis' turn-based strategy game XCOM: Enemy Unknown and 2K Marin's first-person shooter The Bureau: XCOM Declassified as a discounted bundle priced at $24.99.

Downloadable versions of XCOM: Enemy Unknown and The Bureau are available individually for $9.99 and $19.99, respectively.

If you prefer the classic stylings of the XCOM games from the '90s and early 2000s, you may want to check out the $3.75 XCOM Complete Pack, which collects XCOM: Apocalypse, XCOM: Enforcer, XCOM: Interceptor, XCOM: Terror from the Deep, and the 1993 debut entry XCOM: UFO Defense.
