there are similar games at steaM?

Hi all, I have a big problem to unlock the PvP game mode, I have tried everything, single player campaign, campaign co-op, once on easy, medium and hard and nothing, impossible to unlock and 100% the achievement in this game... Someone would have any idea?! I'm looking for someone to share me a save with the PVP mode unlock to be able to finish this game 100%...

I was playing the 1st of the challenges in the game, I think it came from the DLC, and I just noticed one bar on the right and another circle on the left which have one yellow part. Any idea what those 2 bars mean? Picture here: https://i.ibb.co/d5TNNb0/kung-fu-strike.png...

Previously there was no way to change the resolution. This has been resolved. Right-click the game in steam and go to browse local files you should see config.exe there. Click it, choose desired resolution hit apply and there you go!
