Hitman Season 1 is free on PSN. As long as you didn't download the Paris freebie level.
EDIT: If you did download the freebie level: Search for Hitman > let all the Hitman content show up on screen > click on HITMAN™ - The Complete First Season > purchase. (For some reason, clicking on HITMAN™ - The Complete First Season directly from the search bar drop down link only nabs the Paris level.)
Play the FREE TRIAL of HITMAN – The Complete First Season from April 28 through May 3
Assume it'll have an expiry date of Sunday. Still not bad.
If you go into the game once it's loaded, you can then download the Legacy Pack - Hitman 1 levels remastered for use in Hitman 2.
Download the Hitman 2 Free Starter Pack on the PSN Store (this is the first level from that game, but you're downloading the whole thing).
You can the access the remastered Hitman 1 levels in Hitman 2. Presumably they are a separate entity to the freebie on offer, so even if it's a trial you'll still have them.
Though the Internet seems to think someone's goofed and stuck the whole game up permanently for free instead of a trial.
I've only had time to mess around with the prologue, but I have loaded it up in both 1 and 2.
Thanks for the explanation! Downloading the legacy pack now. Do you know if this means we could uninstall the Hitman 1 game afterwards to save space, continuing to play all the levels through the free access to the first level of Hitman 2? Or would Hitman 1 need to be kept installed?
