Average in every way. Not terrible, but not great.
The weapons are pretty weak and must be upgraded to provide any kind of punch. The games AI aren’t very bright either. The enemies tend to attack head on rather than take cover or flank, making kills pretty routine. The levels have interesting layouts for the most part and you need to be sure to watch carefully for the weapon power ups. Most of them are in plain sight but accessing them requires a little bit of thought and exploration.
Overall, Pariah provides several hours of routine FPS gaming, with a few surprises and twists, but if possible don’t pay full price for this game.
