YMMV / Paranautical Activity

• Goddamn Bats: Goddamn Moths that shoot homing shots at you. They're usually more of a threat than some of the bigger enemies or bosses that they occasionally flank. This can be especially bad if you're playing as a character with a projectile weapon as their primary weapon, such as Gilead's chain gun.
• Overshadowed by Controversy: This game is pretty much only known for the incident in which Mike Maulbeck, the lead developer, threatened to kill Gabe Newell over the final release still being labeled as Early Access, which led to Steam taking down the original release and cutting ties with Code Avarice. Discussions of Paranautical Activity to this day are bound to bring this up.
