IO Interactive have been in a particularly jolly mood as of late, it would seem, for even after they've given out the first and the second episodes of their previous Hitman release, they're seemingly going to keep at it for a while yet.
Indeed, Hitman: Episode 3 - Marrakesh (A Gilded Cage) is going to be free-to-claim via Steam starting tomorrow, 17th of July. The offer is limited-time, as all such offers are, though there's been no official mention of how long this promotion will last. If you're eager to jump in and play the third episode of Hitman, best claim the thing as soon as the offer goes live.
Tasked with the assassination of Claus Hugo Strandberg and Reza Zaydan, 47 has to infiltrate the targets' Marrakesh compound while there's a violent riot just outside, thus providing him with plenty of interesting gameplay opportunities which can, but don't necessarily have to include him using weapons at all. As per usual, Marrakesh is a large and sprawling free-form area that 47 can prowl through, seeking his targets out and setting up traps accordingly.
In case you're not overly familiar with how offers such as this one work, to claim Episode 3, all you need to do is open your Steam client, search for 'Hitman: Episode 3' and hit 'install' once the game's page opens up. This will immediately claim a license key for your account, and there's no need for you to actually install the game once the installation window is opened.
