Just checked on PsStore that Hitman is the Deal Of The Week.Glad to see that 7DS is included in the discount as a standalone within the Hitman store.Now that it costs only 6.99€ (it was 9.99 anyway) I guess I have no excuse than to join the late party of this escalation campaign.Time for me to unlock new suits as well!!!
P.S.Anyone know if these 7 new suits work on Freelancer mode too ?
Yes, you can use them in Freelancer!
…why would they not work in Freelancer? If a suit is unlocked to your inventory, then it’s always able to be used in Freelancer, even the Codename 47 suit.
I cannot find it as standalone, only as a part of Deluxe pack. 
Go to the in game store rather then your platforms storefront you should be able to buy them separately in game
So, I just finished a full playthrough of WoA, including the 7DS as they are canonically taking place in 47’s mind between Mendoza and Carpathian Mountains, and I think I have a new appreciation for them that I don’t have at the time. I guess since I’ve improved as a player since then, I had an easier and more enjoyable time playing through them, and more than that, I think I finally understand what some of them were about, particular Sloth and Lust, both of which I could not figure out for a long time what the message of those was supposed to be as they relate to 47. I think I get it now. Alongside the Dartmoor Garden Show, these are the only escalations I actually enjoy.
