OPUS: Rocket of Whispers Switch NSP Free Download One of the more unique adventures to arrive on the Switch eShop in its first year was OPUS: The Day We Found Earth. A charming, story-focused stargaze-‘em-up from indie studio SIGONO, it delivered a shining example of narrative gaming and left us searching for more. Happily, publisher Flyhigh Works/CIRCLE has brought a follow-up in OPUS: Rocket of Whispers. With an all new story and gameplay that swaps star-gazing for rocket-building, it’s a much more melancholy experience, but every bit as affecting as the first. ROMSLAB.COM BEST SWITCH GAMES

Though their shared ‘OPUS’ heading suggests that Rocket of Whispers might be a sequel to The Day We Found Earth, their connection is more nebulous; they may take place in the same universe, but in practice, they’re completely independent stories which happen to share a focus on space. In Rocket of Whispers, you play as John, one of the only survivors of a catastrophic plague. Haunted by voices of ghosts, John’s only corporeal companion is Fei, the last ‘Witch’ responsible for directing the space burials central to their faith of Earthology.
In gameplay terms
That work translates into scavenging via top-down exploration and crafting. Each day, you’ll set out from the rocket factory John and Fei call home to comb the snow-covered town for materials, and return before nightfall to piece together your finds into rocket parts to advance the story, and equipment to further aid your exploration. Crafting a metal cutter might let you harvest more materials or get through fences, for instance, while a makeshift flashlight will help you see inside the now-powerless buildings.Senran Kagura Peach Ball Switch NSP

Your expeditions are ostensibly timed — at least at first — to a single day at a time (about five real-world minutes), but there’s no real way to ‘fail’; the clock serves to gate your exploration rather than to punish or hurry you along. As you explore, you’ll learn more about OPUS’ world and history through a variety of sources: John’s memories, found documents and objects, and the ever-present ghosts which whisper to you as you move around the map.
Apart from the text
That style is further bolstered by OPUS’ presentation, which makes excellent use of a simple art style. It’s childlike in a way that helps soften the dreariness of the world, and its mostly muted earth and sepia tones make the moments of colour that do appear feel truly special. The same can be said of the soundtrack; it’s atmospheric and subtle, with a prominent piano, and often drifts out to leave only the sound of boots crunching in snow before swelling back in.Serial Cleaner Switch NSP

One of the things we loved most about OPUS: The Day We Found Earth was how it felt like a narrative that could truly only be told in a game. That same synergy between gameplay and storytelling is still present in Rocket of Whispers, but it’s perhaps less impactful here, if only because of the familiarity of the mechanics; star-gazing felt utterly unique as a gameplay conceit, but the nuts-and-bolts of scavenging and rocket building — exploration, collecting, and crafting — are standard fare in the medium.
Rocket of Whispers’ story
Rocket of Whispers’ story is carried by strong, effective writing and a charming fixation on information and data; in the former, it was stars, and here, it’s rocket parts. We won’t pretend to know much about the science behind spaceflight even after finishing the OPUS games, but the fact that every item you’ll come across and craft is accompanied by meticulously compiled metadata gives Rocket of Whispers an endearingly unique style.

For us, the journey took around four hours, which felt just about perfect. We had very few complaints along the way, and the issues we did note were slight; the lack of touchscreen control felt strange, but it’s certainly not a dealbreaker (the left analogue stick controls a cursor in the non-overhead sections), and as much as we sometimes wished for waypoints, we also enjoyed having to map out a mental picture of the town as we explored.
