Currently trying to S all the maps with some friends. All I can say is that some maps are bugged (The base game crackhouse, the DLC drugpen and cult map) with guns falling through the map a lot (other maps can have this sometimes but these maps have it constantly), the rest of the game is super fun!
Once you’ve finished all the maps I highly encourage trying non-lethal runs
It has been an issue for years and it doesn’t seem like they’re gonna be fixing it
