Protect Telamon from Zombies

for a long time ... I don’t remember when my friend and I decided to play Protect Telamon from Zombies I don’t know what it was but it was strange we entered the game and after 8-5 minutes I don’t know but we played for a long time, the fog turned black we thought a light bug, and continued to play, but then the zombies seemed to go crazy, they started spinning and resting against the walls .... a silhouette flew by a black silhouette with a large head. And then my friend just walks, but not by himself ... he tried to turn around, but it didn’t work out. Then I followed him towards the tower and there was a strong noise - bass speakers crackled and a friend turned off then the sound "I'm always watching you" and an error, my account could not be restored and it was lost, I thought it was a bug or an error and did not tell but now decided to share. ( i used a  translator  sorry if it's not clear...)
