Hello!
If you watched videos about new projectiles and read my forum messages, then you should know, that I will add this new projectiles in the next update, which will be released soon(Marketplace team now testing it, so it could take 5-10 days before release).
Current demo has almost the same content as current product in marketplace. There is only one global difference and I already wrote about it in WIP thread a lot of time ago: demo has multiple levels, but in marketplace I can only publish 2 levels - showcase and overview. So levels from demo(showcase, arena) was merged into one. Basically marketplace product now has even more content via blueprints because of this merge. I removed one unnecessary level and music track and that’s all as I remember. There is no additional animations, first person character blueprint are the same. Demo works faster, because it was divided into different levels and in marketplace, as I said, I had to merge levels into one big level, so it runs just a little bit slowly. But projectiles works the same and demo is only for demonstration purposes, so it’s really doesn’t matter(usually developers have good hardware). When new update will be released, I will update demo, so they’ll be identically.
All I can recommend you for now is just wait. I can’t do anything to speed up release of update and it’s all depends on marketplace team. I will write a message in this forum thread, when new update will be released.
