Humble Bundle - FREE X-COM: UFO Defense for PC (Save $5.29)

Excellent classic '90s strategy game.!

Humble Bundle offers Steam downloads of X-COM: UFO Defense for Windows for free.

It's the first instalment in the XCOM series, of course, and be forewarned that as far as I can remember it was the first game to make me incredibly angry. The offer is valid for another day and a half, so you'd best go and grab it now before you forget.

Save $5.29 (USD $4).
