I had way too much time on my hands this week...so I thought I would share an initial mapping of Atari's Toobin' (just Class 1 for now since I am using this to decide what new route to take for another 10,000,000+ point 1 credit attempt).
Toobin' River Notes:
Class 1: Colorado, Amazon, American, Okefenokee and Argentum Rivers
Class 2: Yukon, Cuprum, Styx, Left Bank, Nile Rivers
Class 3: Jurassic, Black Forest, Rio Grande, Canals Of Mars and Nightmare Rivers
Class 4-6: the same but much harder difficulty/obstacles/enemies
Atari states that there are 45 different rivers to choose from (different layouts/difficulty for the same ones above)
1. You always begin Class 1 on the same first section of the Colorado River (1). You get to run through five rivers per Class (the longer first river always has a mid section fork + end river fork choice). The end river fork choices from the other two different sections of the Colorado River (2)(3), and those made at the end of each subsequent river, determine how the rest of your game unfolds (left/right black fork choices for the 3 different Colorado River sections).
2 The subsequent river order, map layout, enemy type/location and their difficulty level change depending on whether you take the left (2) or right (3) fork mid Colorado River (then are based on the subsequent left/right blue, green and red fork choices to see where you finish the end of the Class).
3. Every river of the core 15 shown above has at least two different map layouts to learn. The longer Class starting rivers each have three different sections (Colorado, Yukon and Jurassic all have a starting section then a different left or right part two based off the mid river fork).
4. These left/right maps are repeated throughout the game route but each version is slightly different depending on the enemy difficulty/type/locations (different river obstacles and locations for Toobin' letters too). The enemy difficulty of the river maps is based on whether it comes up sooner or later. River difficulty increases as you progress through each Class. For example: If you pick the American River as the second river of five, then it will be much easier to get through than if it was the third or fourth river in that Class. The same river is at the highest difficulty level when played as the last of five.
5. The final river selection, on my map from the fourth river (green) to the fifth (red), only allows you to choose the "left" or "right" map layout of that river. Both will be at the highest difficulty but with a different layout for enemies and obstacles. The river names (multiples of the same left/right maps) are repeated across the top/bottom for the sake of map route clarity.
More to come...?
