About EMS hunted house event.

Now when they got NLC, Do you know/think that they will release it permanently?

NLC, yes, Haunted House, maybe. If they get our version, then yes, if they get KMS' version, then probably not.

No one even know about it, but ppl gess that it will be the KMS event...

Just wait and you'll see in a few days.
No point to discuss that since nobody will be able to answer you anyway.

Their haunted house last year was identical to ours, sans the Headless Horseman, so it's entirely possible.
