The biggest Ghostbusters gathering returns to Portsmouth – bigger, louder, slimier!
Mass Hysteria 2026 is no longer just a single event - it’s a full-scale Ghostbusters charity campaign. This year, we’re taking Mass Hysteria on the road and bringing our proton-packed fundraising experience to three major ComicCons across the South Coast.
From March through to June, Portsmouth Ghostbusters will be hosting Mass Hysteria at multiple events, uniting fans, families, and franchises with one shared mission - to raise a huge amount of money for charity while delivering the most immersive Ghostbusters experience we’ve ever created.
Expect expanded displays, interactive activities, walkthrough elements, raffles, prizes, returning favourites, and brand new surprises built specifically for 2026. Each event will offer a unique experience while still being part of the wider Mass Hysteria story.
Support the cause at each event by donating £5, or by purchasing two raffle tickets for any of our raffles on the day. Every entry gives you a chance to win prizes while directly supporting our charity fundraising.
Visit us at all three Mass Hysteria events in 2026 and you’ll unlock exclusive prizes - because every good Ghostbuster knows you don’t leave a job half-finished.
Follow our socials for live updates, build progress, and behind-the-scenes prep. Charge your packs, clear the containment unit, and get ready - Mass Hysteria 2026 is going to be something special.
The year we made history at Portsmouth Comic Con!
Mass Hysteria 2025 took over Portsmouth Comic Con across 3–4 May 2025, transforming the Guildhall into a full-on Ghostbusters hub. Hundreds of fans, families, and fellow franchises joined forces for an unforgettable weekend of proton packs, laughter, and fundraising.
We welcomed the Southend-on-Sea Ghostbusters and many other UK franchises, hosted kids’ ghost hunts, cosplay contests, raffles, and live talks. Together, we raised an incredible total for Cancer Research UK and broke our own attendance record.
Thank you to everyone who joined us, supported us, and helped keep Portsmouth ghost-free!



The event that started it all.
Mass Hysteria 2024 was our first large-scale charity meet-up – a day that brought together Ghostbusters from across the UK at Portsmouth Comic Con. The energy, the smiles, and the slime set the tone for every event that followed.
From interactive ghost hunts to photo ops with Ectos and packs, it was a weekend full of fun and purpose. And most importantly, it raised vital funds for Cancer Research UK.



A huge thank-you to everyone who made 2024 the perfect launch pad for what became a South Coast tradition.
