Firaxis flipped the premise of the 2012 reboot. The aliens won, ADVENT runs Earth's cities as a friendly-looking police state, and XCOM is a guerrilla cell flying a captured alien supply barge called the Avenger. Most tactical missions open in concealment and run on a turn clock, so ambushes beat slow Overwatch creeping. Everything below covers the base game released in February 2016, with the August 2017 War of the Chosen expansion flagged wherever it changes the answer.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
