Arcade light gun game by
Namco. The game would be
unremarkable apart from two
features.
1. The game was split up into several stages, which had to be completed within a certain time limit.
2. You could
duck behind
objects in every
stage. This was accomplished by
releasing your foot off a
pedal. When you did this, you
automatically reloaded and were invulnerable to enemy fire.
Namco later improved on this formula with the excellent
Time Crisis 2
