Deficio Experimentum is an antagonist in Abandoned Discovery Island.
"Subject appears to be green, it's appearance reminds me of something from a long time ago...It appears it looks like something that came from a rejected horror movie but it seems to be brightly green, if anybody finds this recording. I'll proudly be honored for creating my own 'little monster....' Keep in mind that was sarcasm." -Unknown.
Deficio Experimentum starts at the Lounge instead of the roof, once there it will then sneak it's way into the office, the player must stop him by putting a barrier on either of the two door ways, or he will disable the shutting off power mechanic until 2:AM, putting the player in threat of power-off hungry characters that will kill the player, he does not have a jumpscare. He's just that annoying.
- So basically, he's a failed clone of Nightmare Face.
- "Deficio Experimentum" means "Failed Experiment" because i'm lazy as hell....
- The creator of this "little monster" was then killed 6 hours after making the recording found in the Discovery Island basement.
