The developer races (aka Indian Missions) are a compilation of races created by the developers that were unfinished, rejected in favor of other races, or otherwise unused in the final game. They can be enabled by uncommenting a line in the LoadMissionsTsc file.
How to Unlock
For this trick you need to first navigate to your respective FUEL install folder:
- (Steam): <Steam install>\steamapps\common\fuel\
- (Retail): \Program Files\Codemasters\FUEL\
- Go to "GameTsc\Story" sub-folder
- Open "LoadMissionsTsc.tsc" file (make backup first if you'd like)
- Delete // from in front of "//BSource GameTsc\%1\indianMissions.tsc"
In other words, the line will change from this...
What does it do?
Stargazer's Heights East: An A-to-B raid (around 3 miles) from the top of a mountain into a valley. Very difficult, as the AI racers (all motorcycles) drive in a straight line directly toward the finish, aided by their infinite grip and full speed cheats, while you have to navigate the forests and avoid falling off cliffs.
Stargazer's Heights West: A long checkpoint race (over 10 miles), located near one of the challenges. Aside from the beginning part, which routes you down and up a mountain for no reason, the race takes place entirely along paved roads against other muscle cars. Unfortunately, about halfway through, the developer of the race placed 2 of the checkpoints facing the wrong direction, making the GPS and AI mess up.
Offshore Shack: A checkpoint race (about 4 miles) downhill along mostly road against some an assortment of vehicles. This race is very difficult due to the cheating AI. Unfortunately, the race is inaccessible due to the race gate being in the exact same position as the Blitz Challenge gate. You can access it by manually adjusting the start position coordinates in the Indian Missions file.
The Hangar: A short checkpoint race (about 3 miles) along a road against muscle car AI. Unfortunately, the routing is extremely convoluted, even though the checkpoints are a straight shot down the road, so the AI will go off on weird routes (they will eventually reach the finish, though.)
Roughwood Hill: A checkpoint race (about 6 miles) along varying terrain against some SUVs and buggies. There are some good shortcuts to take, and the race is very difficult due to the cheating AI.
Smokester's Crater West: A checkpoint race on mostly road against some SUVs and other vehicles. Since it is over flat terrain, the shortcut opportunities make up for the cheating AI. Unfortunately, the race is inaccessible due to the race gate being in the exact same position as a challenge gate (it will prompt you to start the race if you haven't unlocked the challenges in this zone, but starting the race crashes the game). You can access it by manually adjusting the start position coordinates in the Indian Missions file.
Smokester's Crater East: A raid (about 6 miles) along road through a forest, against SUVs, and other vehicles. There are few shortcut opportunities due to the density of the surrounding forest, so this race can be a bit difficult.
There is a race located in the middle of open water in Tsunami Reef. Since the race gate is located at the ocean floor, the only way to access the race is to teleport there using the debug tools, while driving the Trident hovercraft. Even though the race is entirely over water, the other AI racers can still win, since they are somehow able to drive underwater.
Essentially you'll see a lot of unmarked start gates showing up (especially around the main drop location for zones and the start locations to GPS-marked career races and challenges). You'll need to ride around a bit to find them, which makes free riding more rewarding when you stumble across a new hidden start gate.
EG1: From Offshore Shack's main drop point (where you start after fast-traveling to that zone), if you head directly north towards the Buggy Speed challenge marker on your GPS you'll come across a road that has start gates spread all over it. Keep riding and you'll notice even more scattered all over. Each of these is a different race: some solo, some competitive (with mixed vehicle class!). However, they all seem to go towards the same Finish Line up in the mountain.
EG2: From Cauldron's Edge main drop point (at the ski lodge race course), you can head down to the street out of the race course. To the left you'll see a start gate. This starts a long, multi-vehicle race much akin to the Raid challenge. The opponents cheat like crazy, so you most likely won't win, but it's fun to race. If you head down the road some, you'll see more start points. There's one for a solo checkpoint race. At the finish to the race by the lodge, there's immediately another start gate that starts another multi-vehicle check-point run.
Don't expect the hand-edited quality of the main career races. These races are treated like Race Editor races. IE: the kind you can make in the editor where you just select race type and drop way-points down. When you win it says "nice race, try editing it to increase the challenge" or some such.
So, don't get your hopes up that you're unlocking some amazing, super-secret 3/4 of the game that'll blow your socks off with quality or complexity.
