Actually, I always felt the opposite. Unreal was one of the last of a real bygone era of shooters where you didn't ask who put all the soul spheres and ammo around Dead Simple. Quite rarely did inventory appearances make any "sense" in Unreal. I think of maybe some of the human ships having some sensible places for stuff, but more often than not you waltzed into areas like Velora Pass where some ancient looking Stone Titan is sitting on a ruined throne, and the trigger that stirs him from his eternal rest is weighted by a weapon upgrade to a prison pistol that only existed on this alien planet like a couple of days before when the player crash landed. Question Mark?

The Source was a typical endgame map for the era in this context. Of course all the game's ammo and best pickups would be horded outside the last battle zone.

The theme looks pretty cool, and manages the "this is the end" atmosphere well (with couple of bonus "wow" touches like the iris door), details like the Pupae hanging on walls are also nice. While the Queen fight can be pretty challenging on Unreal difficulty I do feel like it's lacking something in it's overall execution, but that's probably more a problem with Unreal mostly using lore/backstory rather than major events happening as you play (that could have built it up more).
