Bosses

[graykin]

I dunno, I would kinda consider the room...

Spoiler below!

...where you have to electrocute the Rock Worm to get the scientist's hand...

...to be a kind of boss battle. It's probably the only example in the game (at least, the only one I can think of), but if they did something like that, where you need to use your wits to achieve your goal (of survival) then I like the concept of a boss battle.

Like Power_Infinity said though...not the traditional, Metroid-esque boss battle.

...Not that they'd do something like that in a game like Penumbra or Lux Tenebras, but you never know I s'pose.
