5.13 seems to be an update, but they only added a machine for restoring ammunition after save 2. They removed the rifle from save 3. replaced the rifle with an MP40 at the door demanding a key card a. all ordinary enemies have increased HP (a speararm now requires 11 knife strikes instead of 7, and this is most noticeable). after death and use up, the ammunition is returned. after restarting the exe.file, you still have weapons about access cards, I didn’t check because I don’t give a fuck. Now the boss cannot be killed so easily (probably) with a knife because they added a roll with damage to him and now he moves more.
