XCOM timeline. Elite squad of XCOM soldiers stormed the alien flagship, and prepare to destroy it. Volunteer taked control of the ship, and after viewing destruction and ravage on earth, he lifted ship and destroyed it in the space. Milliseconds before destruction, he dissappearred

Actually, after disapperiaring he come into equestria. Little different equestria...

P.S. XCOM have an AU, where the world united against aliens, world’s best intelligences working together, and XCOM not that sneaky...
P.S.S. Violence tag only for human flashbacks of alien war. Doesnt know about the equestria itself tho...
