Welcome to the strange world of Zenozoik. Meet all kinds of creatures and humanoids, spend a little time punching them in the face... join up with Rimat and save MotherFather... wait... also defeat a Golem, then save the world? I dunno, nothing makes any sense but the fighting is AWESOME!
Proton handles Zeno Clash 2 without any problems. I can run the game on the highest settings without any issues on my GeForce GTX 1060. This game is beautiful and of course created with Unreal engine. I didn't need any workaround or hacks to run it, just download, change compatibility to Proton 5.13-5 and play.
