It wasn't a true 'giveaway'. HSGF is a Twitch channel. In short, you watch the stream to gain channel points which you can convert to store credit to redeem the game, and in return the streamer earns ad revenue from you watching the stream. If I remembered correctly, this game was part of a "Hitsquad Heist" event, which is when limited copies of a game can be redeemed for a 'low' 1000 store credit. Anyway, I'm not posting a link because one, people here have differing opinions of the channel, and two, I myself currently am not in favour of the channel lol. I could tell you more if you want, but only in private. Let me know if want that haha.
