Wonderful game! Insane! Played like 6 hours so far, having a complete blast. Chose the Survivor difficulty and it's harder than real life to get bullets and resources which is ridiculous, changed the resources to moderate difficulty which makes way more sense. Imagine playing through barely using guns, even against armed enemies, then killing up to 5-6 armed enemies and you don't get a single bullet out of them! Before changing the difficulty down to moderate for resources I had many guns and didn't use any and killed a lot with a knife or bare-handed!
So yes, that's not realistic, that's trolling.
Minor problem is it's not giving me surround 7.1/5.1 channel sound, only 2.0 channel although I'm using PS4-certified Astro A40 with the mixer through optical audio. The gore is serious, and I like it, won't spoil even the simplest things, and don't waste your time as you're missing a lot of fun!
