I agree, but to be fair to Frontier, the DLC for Planco1 was called 'Spooky,' and this one is hinted to be called 'Horror.' I hope this is true and we get some blood and guts in the DLC. A huge 'Eddie' from the band Iron Maiden comes to mind, or the giants from 'Attack on Titan'. Or a Jaws attack with splashes of blood on water rides.
This was a store tag not a name or anything,
Like the tag for the spooky dlc, so if some user looking for horror games this dlc will be listed...
All in All, yes it could be a leak, but it could also be 'wrongfully housekeeping' like they thought this tag was missing but removed.
Edit number2: And this is one reason i dont believe, we get anymore free returning themes, cause all other themes are still buyable as DLC for PC1 and i dont think/hope they dont just convert this dlc even for money, if they do it, there should be a huge own spin on it. Though I hope they come up with something completly new that gives PC2 a bit more identity than a simple rehash. IF they do it in any shape or form they really need to deliver as it will compared to the spooky dlc, so a more safe idea is to explore any other theming that hasnt done before.....
