Anyone please give me a guide
Click on the girlfriend and pick the answer she likes to improve her mood and get sex scenes every 4 days. You can't be exhausted, otherwise the scenes will be skipped.
Exploring the building has scripted events that always give specific loot.
-first exploration gives bat
-meet Hyuna and asks what she can offer(2 sex scenes), or ask for other options to block meeting her again on that playthrough
-meet a mother looking for a medkit for her kit(currently no reward/sex scenes)
-looted apartment gives radio or seedlings
-no more events in current version after these
The bat won't protect you from injuries after day 10, so you'll need to find a fire axe by exploring outside before then.
You can click the TV and listen to the radio, and it'll tell you what you are likely to find exploring outside, and how likely you are to get injured.
Seedlings give you a free medkit when the plant grows.(haven't experienced it myself)
For NTR scenes:
-kid: invite the small man in, get the power generator. Ignore his second visit if you don't want NTR, otherwise let him in. He'll propose your gf lives with him upstairs. Choose to let your gf live with him on day 16. Get NTRed.
-Nelson: visit Nelson shop on day 10 for free supplies. Visit again on day 11 with your gf for some light NTR. Survive intruder invasion attempt at night. Visit the shop again on day 13 and Nelson will offer for you to move in with your gf. Survive intruder invasion attempt at night on day 15. Choose to move to Nelson shop on day 16. Get NTRed.
-old man: let old man in. Do
NOT trade the power generator(trading gives some supplies but locks NTR route). The old man will offer a key to one warehouse in exchange for sex with your gf. You must
TELL your gf about the offer once he's gone. Choose to let your gf sleep witht he old man on day 16. Get NTRed.
That's it for sex scenes at the moment. You get saved by default by the hazmat guy on day 20 if you manage to survive all invasion attempts. It seems you need to piss him off at the start in order to get to the car/van ending, as you only get fuel by exploring outside on day 19.
