Here are all the ways you can unlock Caitlyn, the Sheriff of Piltover, as a fighter in 2XKO, including her special recruitment event!
Stoked to play as the Sheriff of Piltover? Here are all the ways you can unlock Caitlyn, the new fighter in 2XKO for Season 1, including a special limited-time recruitment event where you can get her for free.
Unlocking Caitlyn in 2XKO for free
There are multiple ways to get Caitlyn for free in 2XKO. This includes a limited recruitment event, which grants you the fighter just for playing the game.

Cailtyn's recruitment event will be active for three weeks, starting from the Season 1 release. It unlocks the Caitlyn Champion, the Crimson Chroma, and the In My Sights taunt.

To progress this bar, do your Daily, Weekly, and Featured missions, and you'll get her in no time. These also grant Credits, which you can use to purchase other champions.
New accounts are given one Champion Token upon release. You can use this to unlock Caitlyn and some of her basic cosmetics for free. Doing so will consume the Token. While her recruitment event is still active, you may want to rethink using the token since you can use it to unlock other champions, like Vi or Jinx.
Cailtyn's Fighter bundle will be purchasable for 10,000 Credits after her recruitment event has ended.
How to unlock Caitlyn using premium currency
You may also unlock Caitlyn in 2XKO by using their premium currency, KO Points. The same bundle above with the fighter, chroma, and taunt costs 1,000 KO Points (USD $9.99, EUR €9.99, or GBP £8.50).

Additionally, Champion Tokens are also included in the Starter Edition bundles, starting from the standard tier. Unfortunately, this does not include cosmetics for Caitlyn.
If that's what you're after, check out the Season 1 Battle Pass that includes Chromacrash Caitlyn as part of the premium rewards track and Arcane Caitlyn on the Ultra track.
