This brutal 95%-rated Postal spin-off is one of Steam's greatest boomer shooters, and it's just $1 right now

The Postal series is infamous for being riddled with bugs, and gross humor that makes South Park look tame. While critically it scores poorly, developer Running with Scissors wears that pee-covered badge with pride. Postal: Brain Damaged gives the series a new spin, with a different development team in control, and this Quake/Doom-style take isn't just good - it's an absolutely essential FPS game for your Steam library. Don't believe me? Well, it's just $1 / £1 right now, so you don't really have an excuse.
