It's been very quiet on the Gigantic front; Motiga have been working on a lot of updates, overhauls and new heroes in the background, and hopefully they'll be ready to announce them soon.
The current round of beta play is coming to a close on Monday 25, and until then all heroes are free to play, including in-development Pakko!
Motiga revealed that there are actually two concurrent ongoing beta tests — the standard beta that you and I are playing, and a "core" beta where players are individually invited to test more up-to-date heroes and prototypes under NDA.
Going forward, Motiga have expressed the intent to bring a wider playerbase into the core beta to help testing. Hopefully we'll see you there!
