Io Interactive has released Hitman Episode 2 for free (consoles only at present) for a limited time until April 3 2018.
Sapienza is considered to be the best episode of the lot and if you grab it before April 3 it is your FOREVER. If you decide to go out and buy the full game in the future your progression will also carry over to it. Episode 1 has also been available as free download since December last year.
You can Grab Episode: 2 Sapienza from the Xbox and Playstation storefronts (it is referred to as the Hitman Spring Pack on there). Hitman is also an Xbox One X Enhanced title that can be played in native 4k or 60fps mode.
