This game is way harder than 2. Basic ass crap weapons, the necros take 3 xs as much damage, parts n pieces are rare and don't go far, the gun building needs an engineering degree. Think I'm around chapter 8 and 3 hours in, about 20%. Already ran into plenty of the respawn monsters that you absolutely can not kill, those weren't until the end of the game in 2.
Tips needed. I'm sending the scav bot all over he does good but isn't finding enough to build weapons. Have the brightness turned way up and it still a really dark game, can't see walls from floor.
