EVE Online allows you to invite your friends to experience New Eden along with you. If a friend upgrades their account, you'll receive your choice of 30 days of game time or 1 PLEX.
Note: Users with trial EVE Online accounts are not eligible for PLEX rewards, and so will get 30 days of game time.
Send a buddy a personal invite to try EVE Online with you. Alternatively, post an open invite on your favorite social media.
Your buddy upgrades to a full EVE Online account at any point during or after their trial.
After a buddy upgrades you will be able to claim your choice of reward from those available.
