Like Hacknet and, more recently, Orwell before it, Tacoma is a more cerebral affair, one of those investigative types of games where you are an outsider presented with a group of LiveJournal accounts and you must sift through them to find all the juicy gossip within.
Tacoma sees you, an independent contractor who recovers lost AIs for the companies that own them, enter the moon base Tacoma which recently underwent a mild case of catastrophic life support failure, presumably leaving everyone aboard dead and more importantly leaving the base's AI Odin all alone by himself.
Entering the various rooms on Tacoma reveals snippets of surveillance footage recorded by the latent AI that can be downloaded and reviewed, presented as 3D holograms that move around the space. A five-minute block of time will contain more than five minutes-worth of information; for instance, persons A and B might be having a conversation on one corner of the room while C and D converse on the other. When C breaks away from D to talk with A and B, they are intercepted by E who just finished talking with F, while D goes off to do their own thing. You can pause, rewind, and fast-forward through time, allowing you to freely follow whoever you wish to and connect the conversational dots as they go.
Of course, since their actions were recorded as well as their voices, you'll also get to peek over their shoulders as they enter PINs to open doors that are otherwise barred from entry, allowing further access to the juicy juicy secrets within.
What I find really interesting, however, is you actually don't need to engage with any of it. Your character is there to download all the data, find Odin, and get out; investigating the events that led to Tacoma's ruin is not part of the mission. You are entirely free to enter each room, download its data, and get out again, without so much as playing it back once. I don't know why you would, but you totally can.
That is of course not the way I approached Tacoma. I'm sure my employer is displeased with how much time I wasted following each person around from conversation to conversation, but I'm here for the juicy goss; what I found was an engrossing, small but deep story of personal choice when faced with catastrophe, and while there's not really any gameplay or even puzzles in the traditional sense, watching the events unfold and piecing together what actions led to which consequences was enjoyable enough to earn a Fin.
