I'm a huge fan of the Hitman series and especially like the latest versions, with Hitman season 1 being a Games With Gold title I will explain how to get the Legacy Pack for free which is a Remastered and enhanced version of the HITMAN Season One locations.
The Legacy Pack is free for people who own Hitman 2 and Hitman 1.
In Hitman 1 there is a store option where you can buy the Legacy pack for free, you can only do this inside Hitman 1, this shows that you own Hitman 1 and are entitled to the Legacy pack (DRM).
But I don't own Hitman 2, how do get the free pack? Hitman 2 has a free demo in the form of a starter pack, this starter pack is just the first level but it also gives you access to the Legacy missions.
This means you can install Hitman 1 for free from Games With Gold, buy Legacy Pack for free from within Hitman 1, install the Hitman 2 starter pack, then from within Hitman 2 you can download the Hitman 1 Legacy pack fir free.
Now if you want to play Hitman 1 you just load up Hitman 2 and select the Hitman 1 Legacy missions, conviluted I know, but the updated game is worth it.
The Hitman 1 Requiem pack is included.
As you have purchased the Legacy pack for free from within Hitman 1, if your Gold expires you should be able to still play the Legacy missions from within Hitman 2.
