Sarge [Model 0B88]

Released in October 1985.

Considered by some to be the grandfather of all real-time video battle-games, Sarge was the first coin-op game to give players the ability to deploy multiple vehicles against common adversaries and, of course, each other.

Sarge is also probably the first real 'start-to-finish' design collaboration between artist/animator Brian Colin and programmer Jeff Nauman.

From Brian Colin, Lead Artist on Sarge : "The realistically depicted female soldier featured in the game generated so much interest when it was first introduced that, part-way through it's production run, we slipped a hidden player incentive. With the machine's internal DIP switches set a certain way, players who achieved a rank of Colonel were greeted with a winking, sexy GI Jane wearing little more than a smile.
The DIP switches should be set as follows : 0011000100.
To see if the switches are set correctly, look at the girl at the start of the game. If she is wearing a low-cut T-shirt, then the 'hidden player incentive' is on.".
