In both episodes one and two, Charnel House has shown itself to be more of a story driven horror mystery with point-and-click elements rather than the mechanics being the central focus. It used Inhale to draw us in by showing us the characters, then kept us watching with the intriguing Sepulchre addition.

And the final episode in this bizarre, terrifying and wonderful trilogy, Exhale, packs more emotional punch than a truck full of bricks. Seriously, in the seventy short minutes I spent packing this, it managed to play my heart and throat like a harp. The story manages to get even deeper than Sepulchre did, then deals one final blow that will leave you reeling.

Before all that happens though, you're put back into the body of Alex Davenport, who believes that something is very wrong indeed. Much like the opening of episode two, Exhale eases you back into the shoes of the protagonist before it heaps the fear right onto you mind. Unfortunately, it only waits a whole two minutes.

The game wastes seemingly no time before it starts dropping the intensity back on you, as Don, the lovable old man, continues to out do himself with weird conversations. It's not that it's weird for Alex either, it's more jarring for the player to hear. Don recommends going to the meal carriage and getting something to relax her nerves with, after he manages to annoy the ever-loving mercy out of her.

He makes some wild claims that Alex has never mentioned and the two are very on edge with one another, maybe it's because Lang is “asleep” in his room. Before Alex can investigate the cabin however, Old Gloria enters a stretch of tunnel and all the lights on the train shut off at the same moment.

Surrounded by the inky blackness, Alex begins to feel as if her and Don aren't the only ones on the train despite him saying otherwise. Naturally he asks for a naked flame to light the candle he keeps just for this situation. But after lighting it, he immediately blows it out and vanishes from sight, like a ghost.

After Don makes his quick exit, you elect that the best thing to do now is to go to the back of the train and go to the bar. Much be like before though, the cabin door for 2-C is just wide open, waiting to be investigated. Except this time around, instead of a decrepit old man sitting in the rosy seats, there's a small girl, Lydia, practising ballet. Unfortunately she becomes the centre for the brutal finale of the trilogy.

Lydia becomes one of the strange black bags and Alex retreats to the serving carriage confused and bewildered, then becomes even more so as Floyd doesn't show his face. He leaves only a note on the edge of the bar, with a single drink along with it. From this point in the game onwards, events on the train go from oddities into heavier issues that are actually very disturbing to explore in this setting.

There's a part of me that really doesn't want to spoil the huge turn that Exhale dumps on you, but at the same time, the questions that it raises are more numerous that the answers given. During the final minutes of the episode, explanations are given for the events on board Gloria and everything seems to resolve itself. But it's far more brutal than that, what transpires is so disturbing and, in fairness, plausible that it can shake you to your core.

However, our shattered characters never reach Augur Peak, which leaves me with the distinct and unsettling feeling that another trilogy of sequels will be released to the general public in the near future. And to be perfectly honest with you all, I really hope that the developers don't just leave the story there.

I love this entire trilogy though, from the gorgeous 2D pixelated art style to the intuitive control mechanics and especially the high quality voice acting, there's nothing major that I can criticise this series for. The only thing I want now is to see the conclusion or more likely, the next epic chapter, of this storyline.
