Short version: It's the best VR Multiplayer shooter, with game modes and community maps to fill just about every niche.

Long version makes me look like a total sweat but w/e:
- It's got Search and Destroy for Counter Strike fans (and an active competitive scene in VRML).
- It's got Push for fans of Red Orchestra / Rising Storm.
- It's got Co-op Zombies for fans of Left 4 Dead and Killing Floor.
- It's got Hidden for fans of Predator, and Trouble in Terrorist Town for fans of social manipulation and deduction games.
- It's got Deathmatch and Team Deathmatch for Call of Duty fans, and Gun Game, and WW2 weapons and modes and the list just goes on..
Special mentions to custom Halo maps complete with Halo weapons, vehicles and spartan skins, as well as near-perfectly recreated CoD Zombies maps, fully featured and ready to play with friends.

This game basically sells itself just with all of the excellent user-created content and a steady stream of solid updates and support from the game's developers. At the time of writing there's over 2,700 custom maps on workshop for Pavlov and much of that is high-quality content produced by a very passionate community.

Personally, I've tried every VR Shooter on the market. Some are OK, but they all have their issues, generally though Pavlov simply implements most features better than they do. In terms of gameplay mechanics, weapon handling, proper left handed support (THANK YOU), sound, movement and everything else, Pavlov does it best and it's these core systems that lay the foundation for the best VR shooter experience money can buy right now.

In summation, it's good.
