The First Trial

All of a sudden the machine lurches forward, moving in a dimension that's probably created by Humans solely for their interpretation of the universe (Time). Then, decelerating from some un-conceivable speed back down to about 10 MPH. That weird crab guy reappears on the screen:

I SEE YOU DIDN'T DIE ON RECONFIGURATION, LUCKY YOU. I HAVE TAKEN YOU TO THE 1950'S FOR YOUR FIRST TEST;

YOU MUST DECIDE WHICH BRANCH OF 

THE MILITARY TO ENLIST IN (NO, YOU CAN'T PICK "NONE OF THE ABOVE")

Hovering above the recruiting stations, you realize your choices are pretty limited; It's either the Navy or the Army (The airforce is filled up).
