Caustic is a big tank character in Apex Legends. Like Gibraltar, he is a defensive playable character (PC) with some very cool status damaging attacks. While there are plenty of PCs to choose from for free, if you want to play as Caustic or Mirage from the get-go, you'll have to pay.

Can you get Caustic for free?

Yes, you can get Caustic for free but not on the first day. You will need to play and collect legend tokens at each level up. You get around 600 tokens a level so you will need to be at least level 20 to get either Caustic or Mirage for free. If you can't wait that long, or you are happy to give Respawn some money, here is the quickest way to do it.

How to unlock Caustic

Just follow these steps:

  1. Head over to the The Microsoft Store to pick up at least 1,000 Apex Coins.
  2. Log in to your Xbox account to make sure your Apex Coins go to the right account.

  3. Turn on your Xbox One.
  4. Launch Apex Legends.
  5. In the main character select screen press RB to navigate over to the Store tab.
  6. Once in the Store tab, press RB again until you reach the legend tab.

  7. Cursor over to the icon of Caustic, and press A to select him.
  8. Here you can use 750 Apex coins or, if you have leveled up sufficiently, use your legend points to purchase him.
  9. Select Unlock with x, where x is the currency of choice

From here on out, you will have access to Caustic in your character roster and will be able to unlock all of his cosmetics as you play. Despite having noxious gas powers, Caustic has a defender or "tank" role in Apex Legends. His powers work to slow and disorient as opposed to outright poisoning people to death.

These are the only two things you need to buy to unlock Caustic, as the game Apex Legends is free to play.

In-game currency

Apex coins

The quickest way to get Caustic

Apex Coins are the microtransaction currency of choice for Apex Legends. Happily, it is only used to purchase cosmetics, there is no Pay-to-Win here, though you can purchase new Player Characters as well.

While it is possible to get Caustic through the free in-game currency, if you want to play as him from day one you will need to spend some cash. He costs 750 Apex coins but as the minimum coins you can get is 1,000, you will need to at least buy that much.
