Halloween: Something Wicked This Way Comes

A secret base was discovered on Nebelburg and some sort of green matter is permeating the air, emanating an energy no one has ever seen before! Upon investigation, we discovered a portal to another world. As our energy-reading meters got closer to the gateway, the signals grew stronger. Something is in there, and it's trying to break into our world!

The first mission to venture inside the gate wasn't so successful, and we messed up by tangling with these dark forces. Your job, if you choose to accept it, to go in, take all the green matter you can, and get out — so we can close this gateway for good!
