Vortigaunt: "man when I teleported to the earth dimension all I saw were these dudes with two legs and stuff
WHERE ARE THE BARREN ICE FIELDS OF EUROPA?!@"
trenchcoated arctic scout soldiers
offworld troopersssss
and it was the gameplay of the guard (smashing in doors and searching for hiding enemies) that was more interesting to me than the look (though I didn't really mind the model)
cremators
invisible dudes like kupo was talking about
something very large and imposing (ie tentacle imposing, not 'omg strider!!! well time to shoot it to death' imposing)
aperture science robotssssssssss
err rather I mean this was sent to me by a valve employee, that's the ticket
one of valve's least talented employees
omgvip
now that it's raining more than ever
know that we'll still have each other
you can stand under my umbrella?
or you can just have the fire not melt at all
when hitting an icy surface, the flamethrower leaves a decal with a sort of glistening shader, as if the ice has gotten wet from melting a little bit
even if they have melting effects, see bioshock, where the 'melting' was a particle effect and the ice mesh doing an animation
and it looked pretty badass
plus you can use the ol' valve favourite, where a problem causes difficulty early on, but when you get a certain weapon or ability later, it is now easily dispatched (see: manhacks)
gives the player a rad sense of progress and getting back at those dudes who were annoying them so much earlier...
sound, occasional uncloaking, and knocking objects over are all things that show where the enemy is for a moment, but not long enough to get a bead on him
