TennoCon 2018, you can take in most of the Warframe experience thanks to the cache of videos of the event Digital Extremes posted last night. Probably the most important bits are the Railjack and Fortuna previews, but there are several other vids, including the art and sound panels and the cosplay contest.
Massively OP’s MJ Guthrie was on-site for the event; if you’re not into lengthy videos, check out her written coverage and interviews!
