about something: 1, 3 and 4 It's really worth changing.
6 and 9: this would allow you to customize the game more for yourself and your preferences
12: yes, it gives more liveliness to the office and makes the game more interesting and not like before (an empty office and you're alone and no sounds)but sometimes it's better to listen to music than unintelligible noise
5: what can be bad in simple costamization?
and from me: its was be interested to se somithing like secret gamemode ( to speak somthing like ultra hardcore).
1) monsters now REALLY scary
2) map in blood, bones and something like this
3) yes baby you cant use spray
4) tools can break down and you cant use this again
5) monsters now more faster and can hear you
its all :D
