Tunnel Runner [Model 4L 2520 5000]

Tunnel Runner is Balaska's first game for CBS Electronics.

The little symbol that appears on the title screen is actually the letters db (for Dick Balaska).

Starting on run 9, each run has a secret door with the initials db and cb (for the programmer's former wife, Cindy) on it. If you run up to the door, you’ll get about 1,000 points, but if you turn away after first seeing it, you won’t get any.

An addendum sheet was later included, which corrects some errors in the manual, since the game was changed prior to being released.

To execute an emergency transport, hold FIRE and rotate the joystick in either direction during a run. Note: This may only be done once per run. This feature is not documented in the manual.

* Keep your ears open! The more familiar you become with each Maze Zot's characteristic sound, the better you'll be at making quick decisions to run or wait without having to check the Map.

* Learn to run and turn without stopping. Turn into a corner in advance of actually coming to the intersection and push up on the Joystick immediately after making the turn. You'll be able to keep up your momentum.

* Don't spend too much time staring at the Map. Remember that the maze Zots are constantly in motion and you're prevented from moving as long as the Map is on the screen.
