Just noticed this game is released on Steam, apparently it was on GreenLight but somehow I missed it. It’s basically free Half Life 2 mod, and from what I gather, it’s basically adventure games so I’ve given it a download; may post my impressions later on. In meantime here’s full information from store page:
Estranged tells the story of a lone fisherman, whose ship is stranded on a mysterious island during a violent storm.
Explore the rich environments and meet the curious inhabitants of the island as you find a way back to the mainland. Face both danger and intrigue in this perilous adventure, where you will soon find that not everything is as normal as it seems.
And here’s the trailer (although it does seem to have some spoilers, watch at your own risk)
I’ve been always wanting more adventure games that focuses on exploration/story so this looks like good game for that.
