The Crew 2

This is pretty simply but, it'll take some time. You just have to complete one of each event listed under each family. There are four types of events listed under each family but, there are quite a few to pick from. You only need to complete one from the given list and you MUST get the objective or it will not count.

Street Racing:
- Street Race
- Drift
- Drag Race
- Hyper Car

Offroad;:
- Rally Raid
- Moto Cross
- Rally Cross
- Hover Craft

Freestyle:
- Aerobics
- Demolition Derby
- Jet Sprint
- Monster Truck

Pro Racing:
- Power Boat
- Touring Car
- Alpha GP
- Air Race

For Street Race, Rally Raid, Aerobics and Power Boat, you will get free vehicles. Every other event, you will have to save up money and buy vehicles. Thankfully, money isn't that hard to earn. For Monster Truck, skip the first 2 events and do the 3rd event.

For Drag Race, skip the first event as it is near impossible to do with a stock drag car. Closest I could get was within 2 seconds of the target time. Use your nitrous right at the start and then fly through the gears. As long as you get GOOD or PERFECT shifts, you should be fine.

Ideally, you should spend some time exploring the map looking for live crates. They offer anywhere between 4 and 7 upgrades for your vehicle of choice so, please make sure you are in the specific vehicle you want the parts for as they are not transferable between different types of vehicle. Street Race car parts can be swapped between the same Street Race type cars but, are not transferable to any other type of vehicle. Same goes for other vehicles.

The best way to do this would be to hop into the free plane you get from the Aerobatics event and just fly around the map until your radar starts pinging. Switch to a ground vehicle and go exploring. Your map will ping faster and faster the closer you are to the live crates. You can't use the live crates on power boats or jet sprint boats seeing as they're located on land. Unsure about planes.

Events from the Live Xtrem Series aren't required for the achievement. After you complete your final event, the achievement will unlock a few seconds later.
