The XCOM series of computer games (the original game has also been known as UFO: Enemy Unknown) is one of the best series of turn-based strategy games, in which the player controls Terran forces fighting an alien invasion, be that from a base on Mars, from underwater or from another dimension (or an orbiting starship). The games combine strategic globe and base management with tactical combat in which a squad of Terran soldiers kick some serious alien ass. They are tremendous fun, and also highly inspirational for wargaming and RPGs, and one of the sources of inspiration for my Visions of Empire setting for Classic Traveller. In 2012 a remake/re-imagining of the first game was released, also with great success.
And now, 2K, the studio responsible for this excellent game, has released a cryptic web-page of the "Advent Administration", a supposedly "Utopian" government promising futuristic cities and gene therapy. This site was supposedly "hacked" by people who wish to reveal the ugly truth under the Advent's glossy facade. This is the setting for the next XCOM game - an Earth controlled by alien overlords, where a resurgent XCOM wages a protracted guerrilla war for liberation of Mother Terra from the alien overlords, as seen in the reveal trailer. Much like my Visions of Empire's setting EFA (like the Advent, a puppet government controlled by alien masterminds) being fought against by Terran rebels and the Terran independence movement. Though in my Visions of Empire setting, the EFA was overthrown relatively quickly by a mass uprising led by the Terran Coalition; the real fighting occurred afterwards, between the newly independent United Terran Republic and the Reticulan Empire bent on bringing Terra back under its control.
But anyway I rejoice at a chance to fight for Mother Terra and against alien slave-lords! Long live XCOM! Long live the UTR!
(on a side note, this XCOM game could inspire tabletop skirmish wargaming of small Terran guerrilla units fighting alien overlords...)
