Looks like you can unlock Apex Legends Twitch Prime loot without needing a subscription
An Apex Legends player has discovered a simple way to earn the Twitch Prime loot in-game without having to subscribe to the service.
In case you missed it, Apex Legends and Twitch have partnered up for a special promotion. By linking your Twitch Prime account to your EA account, you immediately get a free Pathfinder skin, and five Apex Packs.
Simple enough, but according to @Adam_THR, you don't even need an active Prime subscription. They discovered that if you put a special line of code in the game's launch options on Origin, you'll achieve the same result.
To do this, click on the Apex Legends tile in Origin, hit launch options, and enter this code: +twitch_prime_linked 1. The next time you launch the game, you should see the loot.
This is obviously not the official way to do it, and it's likely going to get fixed. But, it's there if you really need your Pathfinder to be purple.
Thanks, PCGamesN.
