If you're a fan of the two modern XCOM games and would like to take a look at how all of it started, you're in luck as Humble Bundle is giving away X-COM: UFO Defense for the next 16 hours. Simply head on over to the Humble Store, log in or create a new account, and that's pretty much it.
Before you dive in, however, it is important to note that the classic X-COM is much sillier and lighthearted in nature than the modern ones. And if you're wondering how silly a game about alien invasions could possibly be, allow me to share with you the intro cinematic... its quite something! Have a look:
And for those of you that don't own XCOM 2, but would like to correct that 'mistake' in the near future, you might want to take a look at the currently ongoing Humble Monthly Bundle. By spending $12 now you'll be able to get XCOM 2 immediately, as well as a bunch of currently unknown games in two days once the bundle finally closes. Given how XCOM 2 is still pretty damn expensive I would say this offer is definitely worth it, just make sure to unsubscribe if you're not willing to pay for any further bundles!
