@LittleTom @beardalaxy That's horrible. The game literally makes no sense on a first play through then. I was wondering if I missed something.

I recently played through Marathon, a 90s shooter made by Bungie. The entire story is accessible on a first playthrough, though you are not likely to find it because they are hidden away as secrets, usually requiring special tricks to reach them, and the instruction on how to perform these tricks are themselves hidden on the second to last level.

However, on a first play-through the story is easy enough to follow: you are a security officer defending a colony ship from Aliens. One of the ships AI has gone insane, so it's up to you to try and stop both to save the ship and it's crew. There is the hint of a bigger conspiracy at play, leaving questions for the player, but nothing that makes the story incomprehensible.

The game is "fun", so you might replay it, and ultimately encounter the secrets, filling in the gaps the story has. At the same time, it never spells anything out. For example, the fact that you are a robot can be inferred by context (one terminal mentions that someone smuggled 10 "battleroids" on board the colony ship, and at the ending monologue it is mentioned that 9 battleroids fought against the aliens on a nearby planet that you had just happened to be leaving when the game starts), but it's never explicitly spelled out for the player, and the gap between those hints are great enough for the player to not make the connection unless they were taking notes.

This is the right way to do it.
