Ahoy!
Apologies, we've spent the last few weeks getting out feet back under the table and I only just saw this as we started prepping for GameBlast. @beckyfr0st and I will be looking at an asset pack refresh as soon as we can but it is VERY bitty work which is why it has been inconsistent. We're really going to try and change that this year but we ask you just be patient as it can be quite challenging to make sure you get approved assets that aren't under NDA etc.
All assets currently available are here but are no longer split into Seasons, but category so you can find SFX, visuals, GIFs etc. It is out of date though so will take some time to refresh with the missing seasons.
