Ideally, you want to try to keep things balanced when it comes to upgrading. However, some things will seem more appealing than others.
- An Engine upgrade means you can accelerate faster as well as benefit from better fuel efficiency. Both are great for making progress faster, so try to make this a priority early on.
- Upgrading the Transmission increases your maximum speed. Again, it’s pretty useful as more speed means you cover more distance.
- New Wheels means better grip, which leads to being able to go uphill more effectively. In early levels this isn’t such a big deal, but later stages tend to be more hilly, making wheels a much more important upgrade.
- Buying a Gun means you can automatically shoot at zombies until you run out of ammo. Ammo supplies are always very limited, and while you’ll earn more money this way, it’s not overly helpful. Leave a gun upgrade till last.
- Buying a Booster is great. It’s relatively inexpensive and means you can speed up through certain obstacles or over ramps. It doesn’t last long so it’s not as useful as an Engine upgrade, but it’s still pretty handy and worth upgrading occasionally.
- A Weight change mans your vehicle’s weight is redistributed, meaning it’s easier to break through stuff like barriers and zombies. It’s a subtle improvement but moderately useful, especially if you keep finding yourself getting stuck amongst blockades.
- Armor means you’re less likely to be significantly damaged when crashing through stuff. It’s not an early priority, but soon enough you’ll find you’re failing because your vehicle is falling apart. This is when an armor upgrade is essential.
- Upgrading the Fuel Tank is pretty self-explanatory. More fuel means you can travel further, which is the whole point of the game. It’s an important one.
- Once you’ve maxed-out everything, you gain an extra engine boost so make sure you don’t bother stockpiling any money. Earn to Die 2 is designed in a way that means it expects you to mostly max everything out in order to move onto the next stage.
