Thunder, thunder, thunder!
As February comes to a close, we are entering the final stretch of preparing both the core book and the adventure book for you all. We’ve been hard at work assigning art for the core book and bringing the adventures together, and we are currently awaiting final approvals before moving into the finishing touches.
Adventures
The adventure book features five adventures, one for each era of the ThunderCats saga:
The Welcome Party (Exodus era). Explore the underground temple of a dangerous cult to rescue Thunderians lost after their crash on Third Earth.
Don’t Thorburn Your Bridges (ThunderCats Ho! Era). Recover and protect a unique package through gang-filled badlands to deliver it safely.
Capture The Flag (Return to Thundera Era). Infiltrate a heavily guarded spaceship to retrieve a piece of the Treasure of Thundera and liberate a friend.
Berserker Rage (League of Third Earth Era). Defend a peaceful village from Berserker raids, then carry the fight to their warship to reclaim the stolen plunder and restore it to the people of Third Earth.
Mumm-Ra Must Die! (ThunderGuard Era). Delve into the Onyx Pyramid on New Thundera and end Mumm-Ra’s threat once and for all.
Release Plans
Our goal is to have everything ready for print by the end of March. PDFs will be released around the same time so backers can begin exploring Third Earth as soon as possible. If all goes according to plan, physical books should arrive in your hands this summer.
We truly appreciate your support and patience as we’ve worked through the production and approval process. We are incredibly proud of what we’ve created and cannot wait for you to experience it yourselves!
