Hey all. Always enjoyed reading everyone's suggestions on more unknown games available during big steam sales.
I'll start off with one that I have been a fan of for a long time: Death Road to Canada
This game is like a zombie action Oregon Trail like game, where you manage supplies and fight through hordes of zombies on your way to the safe haven of Canada. Only US$3.74 right now and well worth it imo!
Ok, not so much as hidden, but also not super known: Shadow Tactics: Blades of the Shogun. A tactical stealth game (think commandos saga back in the day) is 90% Technobabylon. A pixelated point & click adventure with some cyberpunk themes at 70% Return of the Obra Dinn. Probably the best detective/deduction game that I've played, at 40% Prey. One of the best immersive sims, at 75% The Case of the Golden Idol. Is not as good as Obra Dinn in my opinion, but it's super good none the less, at 30% Antichamber. Super good puzzle game, at 75% The Age of Decadence. Ultra hardcore RPG set in ancient Rome, 60% Tametsi. Is like minesweeper but good, 67% (and only 0.77€)
Absolute gem of a game, shame Bethesda forced them to use the Prey branding; a lot of fans of the original wrote it off because it has nothing to do with the original. One can't help but wonder if we would've had such a disaster as Redfall if Colantonio hadn't left as a result of all that.
Underrated even among Prey fans is Mooncrash, easily the best roguelite experience from a AAA studio, and just a great experience all around for anyone who wants 'more Prey'.
