Survive/fight the guard(s) until morning arrives or just kill them.
Find some stuff in the mart, foods, and weapon.
Smart guards AI.
The guards don't have only one sometimes and they have to eat and drink too.
Do the objective to start a countdown (similar to asymmetrical games LMS where you have to survive around 1:20 minutes).
Yoo this is similar to something im doing
Its called "final recording" and its about surviving different analog horror monsters
In the first version,its gonna be vita mimic and if you are the last one alive,a gun spawns and one elder mimic spawns
Id really appreciate any support
