What PvP would you suggest for contest in VR-club?

Hello everyone! I have a small problem - I'm from russia, and here VR is not too popular. I got a VR-club (4 HTC Vive) and every month we do some contest between our clients for cool prizes.
First contest was - Arizona Sunshine. Which command earn more points (survive more waves) - those will win
Second contest was - Elven Assasin, PvP - people really liked it! Killing each other was really cool expirience.

But I don't have any Idea what game offer in this month. I'm already watched 100+ video reviews on youtube, but they all have problems (no PvP mode / only early access for 100$ / no multiplayer)

Help me please, tell what games do you like to play with your friends? Preferable PvP, but survival is ok too. Thanks for your help!

How about Sparc? It appears to be fun to play (they don't support my headset so I can't play), AND its even fun to watch! It's sorta like if you mixed tennis with dodgeball! Really cool game!

I tried Skyfront and enjoyed it. It seems like it would be a good tournament game https://store.steampowered.com/app/640800/Skyfront_VR/
