"Firaxis’ reboot of XCOM, Enemy Unknown, is one of the most logically sound alien invasion games you’ll ever play. It accepts that if extraterrestrials were to invade the earth, it wouldn’t be a single soldier in a suit of armor that fights them off by blasting his way through their defenses. No, it would require a multinational organization dedicated to researching the aliens, building the tools to defeat them, and engaging them in strategic battles to fuel the resistance. It also admits what most invasion stories won’t: The fight wouldn’t be easy, it wouldn’t be pretty, and there’s a good chance the human race’s attempts to destroy their invaders would fail horribly. It’s from desperation like this that true greatness becomes possible."

Amazon Prime subscribers can claim free PC games to keep via its Luna service.

XCOM: Enemy Unknown rebooted the series back in 2012, and has since inspired numerous new strategy game series to be born.
If someone gets into this I'd recommend getting the enemy within version. It's got all the dlc included so it's the better version. Wish the author would've atleast mentioned it. I didn't see it.
Fantastic game though. Xcom 2 is top notch also. I've spent countless hours in these games.

There are few things more gratifying in gaming than skillfully turning the tide of a conflict. And few genres provide as many opportunities to abruptly reverse the odds via skill and forethought as tactical strategy. To be sure, we are more often than not talking about turn-based tactical mobile games, specifically titles in line with the iconic landmark series (XCOM and Jagged Alliance) that made the genre a genre.
