Hi and welcome to an easter egg from the 1997 version of Timeshock! the original game.

Thanks to Youtuber "Generally Inappropriate aka.FM" and his video about the secret mode, this guide exists, although not re-tested yet on the definitive Ultra version of the pinball but it was still present during Alpha and Beta of the re-release.

If anyone on Steam gets to exactly follow the steps and confirm that this secret still carries on or not with the new version, it would be greatly appreciated !

Firstly :
(For these 2 first steps order didn't matter, to be confirmed in new version)
- Get to the Prehistoric Age and trigger the quickshot mode. An Asteroid will be the 5th souvenir in that era. Get it.
- Advancing to the Future trigger the quicksot mode once again, get the hologram projector that is the second souvenir available in that era.

- When you get the 2nd souvenir, you should hear a cow muggling. Light the S-C-A-N at the right and left of the bumpers and shoot for the Crystal. It is to be noted that if this SCAN was to be a super scanner, your souvenirs wouldn't get combined ! So get SCAN once more if that was to happen.

- Next time you get Video Mode, it will play normally. Except for a few things, you will play all 3 parts of the video mode at once, and the usual sprite of items to collect will be gone replaced by ... Cows ... why ? it's still a mystery, the forum didn't hold the answers back then and that's pretty much about it ... enjoy the "moos" & don't forget to get the Extra Ball :P
