Read the fine print before you use your PC Warframe account on Nintendo Switch

Warframe is out on Nintendo Switch, and the free-to-play third-person shooter is absolutely worth a try if you’ve never played it. You can even migrate your account from the PC version to your Switch if you’re already a fan and don’t want to start from the beginning.
Don’t expect cross-platform play, however, and here’s where it gets a bit strange: Don’t expect your progress on the Switch to carry back over to the PC. Migrating your progress from the PC to the Switch basically means that you’re splitting one account into two, and neither have any way to talk to each other. So progress can be moved from one platform to the other, but only once, and only in one direction.
