PS4 version is buggy in every way. The difficulty when playing solo on CR2 or CR3 of the first level is nearly impossible. You can't leave with loot and then come back with better gear so you're forced to play a set time length.
From a singleplayer perspective it's terribly designed. It's pretty but poorly optimised. Wasted hours trying to give the game a second chance; add local multiplayer and it will be a decent game. Until then it's a complete waste of time and money
