I am working on a small SP adventure horror mini-mod for the Source Engine. I don't want to reveal too much about the storyline as it would kill the mystery of the plot line. :P What I can tell however, is the storyline is not related at all that of Half-life 2, nor will it focus on action, rather more on exploration and discovery with some horror thrown in for good measure.
I have released two smaller maps that contain clues to the storyline.
Cryptos-1: Cipher has been broken (http://www.interlopers.net/forum/viewtopic.php?f=3&t=21910)
Cryptos-2: Cipher has yet to be deciphered. (http://www.interlopers.net/forum/viewtopic.php?f=3&t=22070)
Everytime the cipher has been decrypted, I will post another update with another clue.
Now onto the media:
Some areas are still very WIP as you can see, but any suggestions would still be appriciated.
