Ran this module over the weekend, with two friends that hadn't played before. Nice module for beginners.
I ran with Hilarion as the only living soul, hiding from Opollo in the warren of ducts in the rear part of the ship. The time shenanigans were nice; in an early attempt to load the child onto their ship, they returned to the airlock to discover it hadn't arrived yet.
Ended with a chaotic escape, Opollo doing everything he could to stop them, Hilarion getting killed in the process, with one player saved at the last minute by a critical success from the other player.
Looking forward to seeing your next project
Thanks for the review!! We're working on something new that will be out soon)
This webpage is missing the title of the module in the header.
Thanks! We missed that point.
Just ran this. The soundtrack is totally appropriate for the setting. The real life countdown clock heightens the tensions and adds another element beside room activated events. The VTT assets weren't used since mothership is mostly theater of the mind, but I wished I did use them.
Would definitely run this again for any group; super beginner friendly.
