River Patrol © 1984 Tigervision.
You are captain of the boat trying to make it upriver while saving the drowning people lost in one of the nine rivers. The more people you save the more points you score, but your boat leaks so watch your water gauge.
Based on the obscure coin-op by Kersten. River Patrol is a rare game as well.
The reason behind River Patrol's rarity is unclear, even though it was the fourth game planned by Tigervision (appearing in their first catalog) it was one of the last games to be released. There are several theories behind the delay ranging from the programmer having difficulty programming the game to licensing problems with Kersten.
There are 3 ways to score.
1. When your boat passes a certain mileage in the course, 10 points will be awarded.
2. A bonus is awarded when you reach the dam. The final state of the water gauge determines the size of this bonus.
3. For each drowning person your boat successfully saves. You are awarded an increasing bonus. The bonus Starts at 50 points and increases by 50 points for the next person, i.e. 50, 100, 150, 200 etc. If you fail to save a person, the bonus is reset to 50 points.
