Our final game at Immersia was their latest and flashiest. The St-Onge Case is a direct but standalone sequel to Weekend at the Shack, the first game we played that very same day. The premise is like something you might see in a thriller film franchise. Set 10 years after the events at the shack, the titular psycho killer is now in prison, but your fellow escapee from that fateful day, Alex, still wants revenge and needs your help! So how was it?

• Wow. The St-Onge Case was epic! Having played 5 Immersia rooms by the time we stepped into this one, I felt like I already had a good grasp of their game style and design. All of their games were of a similar quality, size, and had similar production values and live-actor interactions. But The St-Onge Case was simply on another level. This was a sprawling, multi-space, highly diverse experience with a wide range of puzzles, narrative depth, and cinematic moments. Immersia allocated a lot more space, budget, and attention to this game than their previous ones, and it showed.

• First of all, this game was massive. We started off in an unassuming crime lab, which made me feel like the game was going to go in a certain direction. But from there, things just kept ramping up and taking new turns, and each fresh space delivered a different environment with a different set of corresponding puzzles.

• The was one particular moment when we opened a door and were dumbstruck by what appeared in front of us. It was one of the most awe-inspiring moments of our entire Canada trip (and yes, that includes Escaparium!). Immersia has the advantage of high ceilings and I'm glad they made the most of it.

• The puzzles were fantastic too. There was a very wide range of puzzle types, and thanks to the ever-changing setting, all of them were diegetic or at least aligned with the theme. Hunt and seek, reading and observation, computerised sequencing, tactile blocks, logical deduction, lighting, optics, identifying and following prompts, and multiple teamwork puzzles — this game had it all. Some were straightforward, some were complex; others required careful attention to detail. There were maybe a couple of puzzles in the second half of the game where more signposting would have been welcome, but on the whole we found the flow quite smooth.

• The tech in this game was also fantastic, not just in terms of the media, props, and electronic equipment that form part of the puzzles but also the narrative devices and special effects.

• Interestingly, unlike other Immersia rooms, The St-Onge Case did not have a pre-game intro video or a true live actor presence, but there were other in-game media and various cool tricks in place of these things. They did a great job of making things appear as though they were happening in real time to add a sense of tension and urgency.

• While it is not strictly necessary to have played Weekend at the Shack first, I would highly recommend it. Not just because it makes St-Onge Case a much more complete and satisfying experience due to its numerous references and nods, but because Weekend at the Shack is a great game in itself. Moreover, they are actually very different games that belong in different genres. If Weekend at the Shack is a slasher film, then The St-Onge Case is a mystery action-thriller with horror elements.

• However, there was one puzzle in The St-Onge Case that had a tenuous link to its predecessor — but ONLY if you had used the hint system. But since we didn't, we were confused and needed a hint from our GM, who said afterward that this was a puzzle they were reconsidering.

• In sum, The St-Onge Case is Immersia's magnum opus, their most TERPECA-esque room. I'm a little surprised it fell far short of Top Room status in 2025, coming in at No. 216. Maybe it was too new at time of voting. I hope it will fare better this year because it deserves it.
