If you don't already own Shadow Warrior, Hotline Miami or, most importantly, Hatoful Boyfriend, then now's the time to snap them up. Devolver Digital is having a weekend long sale on most of its Steam games, with 90 percent off some titles. That means you can get Serious Sam 3 for a measly $3.99, or The Talos Principle for $13.59 (its expansion is there too, which comes with the Chris Thursten seal of approval).
It's also a decent opportunity to get OlliOlli 2, which finally launched for PC this week. You might also want to catch up on Shadow Warrior before its sequel arrives next year – it's only $3.99. The full sale listing is over here.
