I played the entire solo campaign and also multiplayer, running at max settings. It's a very solid Proton title! Platinum for sure. The only way to play the first and second chapters is though this game, which contain remastered versions (the original games, NZA and NZA II, don't run using Proton). The launcher is glitched and shows a blank background with links, but everything works fine after selecting "play". Amazing game!
