Just Cause 2

Challenges are races. They will pop up on your map inside faction territory. This means that in order to have access to the challenges you first need to do takeover missions for the factions. Once done, navigate to your PDA map. You will notice a flag symbol. Those are the challenges who amount to a total of 75. For this achievement you will need to pass 2/3 of all challenges. I therefore suggest that if you fail a challenge, move on.

Approach the location and look for a flag post that is eye-high. You do not need a vehicle to start the race as it will be provided. There are different types of races requiring different vehicles and different skill levels. You will see all this information on a confirmation screen once you pushed near the flag post.

The actual races are checkpoint races. For every gate you will get a time bonus. Your finishing time does not matter as long as you don't run out of time. Vehicles can be wrecked during the race as long as you can replace them before you have not enough time left to finish the challenge. Take note of the vehicle type. You will get a message at the start of the race informing you explicitly that only specific vehicles can be used. Only those can be used to cross the checkpoints. The categories are air, road, water and foot.

You can find the provided vehicles near the flag post. They will be easy to spot most of the time. Take your time and look around as most of the time they are best for completing the challenge. The race will start once you cross the starting line.

For those of you who struggle with some of the races I put together some general advise:

- When you start the challenge you will also spawn a vehicle. Most of the time it is a good idea to use that one. However you are free to choose. Just remember that once you start it you will be restricted to a certain area before the challenge fails so be sure to bring your vehicle to the flag (and don't park it where the other one will spawn or yours will despawn) before you start the challenge.

- When you start a challenge you will despawn all nearby military units. This comes in handy. Just remember that your Wanted Level will not drop and that the military will most likely just be around the corner to shoot up your tires. I advise starting challenges only when your Wanted Level is all the way down.

- Ground Vehicle challenges; remember that you can switch vehicles at any time. You only have to be in a ground vehicle when you cross the gates. You can parachute to take shortcuts or switch if your vehicle is damaged. Calling in a vehicle from the Black Market is also sometimes a good solution when you are in a secluded area.

- Boat challenges; It is easier to take turns when releasing the throttle. Sliding over land will slowly damage your vehicle. Don't do it too often except when the challenge is designed in a way where you obviously have to.

- Air vehicle challenges; most of the times it is easier to go with helicopters than planes. Especially in the city area. Try using planes and when you find it to hard, go with a helicopter. I suggest picking up the small one from the Black Market. It has not much health but it is really fast and handles well when upgraded.

- On foot challenges; most of these revolve around base-jumping. It is basically trial and error. Just remember that you are allowed to parachute and grapple. Anything is legal as long as you pass the gates in time.

If you are having problems completing a particular challenge with the recommended vehicle...try out a helicopter.

You are not bound by the vehicle type. You can complete the challenges with any vehicle you can get through the rings. This includes some of those particularly evil Base Jumping challenges!

I recommend an upgraded Rowlinson K22.

Doing this achievement also adds % to your game, so if your planning on going for the 75% achievement, then do this.

Take care of your vehicles. Especially the buggies, that tend to blow up. Nothing worse than losing your fast car on the really long runs.

Airplane challenges are easy, just steer clear of the large poles and swing back in for the ring.

Boat challenges - MAKE SURE you stay on track, otherwise you've pretty much failed. Turning in boats is unforgiving.

I found some of the challenges quite hard.

so some tips;
stick to the 1 and 2 star difficulties.
only do a handfull of 3 star. (to make up the numbers)
avoid the base jumps (try but i found them the most difficult).

Use the buggy thingy for land clallenges (from black market).
The Rowlinson (from black market) for air (can also be used for land and sea).
Vehicles can be orderd during challenges (just in case yours blows up)
Upgrade the vehicles you use the most.

Use the cars provided and just hit the circles. simple stuff.

some of the skydiving ones are a pain in the ass, but only take a few tries.
For the flying ones use the fully upgraded red and black little helicopter, it is fast enough when upgraded to make it through all of the races.
