I think the Metro series from 4A Games are some of the tightest, weirdest, and most immersive first-person shooters on the market right now. But while Exodus is my favorite, it’s hard to recommend for anyone looking for a horror game right now. However, the first two games in the series—Metro 2033 and Metro: Last Light,—are both much more linear and scarier titles.
Both are mainly set in the claustrophobic tunnels of the Russian underground, which are plagued by monstrosities and supernatural phenomena that lurk in the dark. Encounters against these creatures are regularly fraught with tension, and both 2033 and Last Light lean more into the rhythm and pace of the horror genre, while sprinkling in doses of human drama and psychological terror. They’re also, crucially, shorter games, meaning that you can reasonably pack all those scares into a weekend. Metro 2033 and Metro: Last Light are each discounted to $3, or you can pick up the bundle of all three games for $9.
