Underground Base Escape

This is a text-based adventure game. You wake up in a laboratory and lose all your memory. You walk through the rooms, check and pick up items to achieve specific tasks, such as opening a locked door, killing a monster, playing a video etc. Gradually, you will find the truth of your memory loss and get touched by the sorrowful love story. However, if you wander for too long, and don’t win the game within the limited time, the underground base will explode and you will lose the game.

4. Tina’s Diary (1)

4/Feb/2069
It’s the first day Peter come here. I’m so excited as he was not the strongest guy among all
the soldiers but did be selected by Dr. Josh. How honoured! Doctor even agreed to let me do
the injection! I even reset the password of the exit to our wedding anniversary. I’m sure
Peter will be surprised when we leave here together after he finishing the experiment.

9/Feb/2069
It has been 5 days since Peter got injection. He is obviously stronger than ever, but always
feel sleepy. Dr. Josh said it’s normal, as his body was auto-repairing. Hope this period will
not last too long, as I can’t wait to go home with Peter to see our lovely baby. I miss her a
lot.

15/Feb/2069
Things get different. His conscious hours become fewer and fewer. I’m so worried but Dr.
Josh insisted it’s ok.

5. Tina’s Diary (2)

27/Feb/2069
That’s a nightmare. Peter suddenly woke up from a coma and killed all the people out of
control. He must remember me as he didn’t hurt me at all. Dr. Josh escaped, locked the exit
and started the explosion program. Fortunately, I found how to save Peter in Josh’s office.
He will be fine, although I may have no change to see him and our baby again. I’m not sure
what monster I will become, but I’m afraid I may hurt him. This is why I locked myself in this
room. Anyway, Peter, I love you.

6. Necklace

A small wedding photo with “16/Dec/2064” written on it is embedded in the necklace. You
find the woman is the zombie you just killed and the man you feel so familiar but can’t
remember who is he.

of the nuclear radiation. I had been trying to find a way to resurrect her, and finally I got it.
Peter is the one who’s critical genes segments are similar to my sister. So, I chose him for the
experiment. If successful, human would no longer be afraid of nuclear radiation and I would
