I said ENTIRE feature list.

The creator will have to explain that.

Probably no point being it explained

this is the same as the one in the description...
ITS NOT THE ENTIRE ONE D:<

Couple of unmentioned things i've found so far while playing through the first couple maps:

Your heath regenerates, though i don't know the specific mechanics.

You get sound effects used by the Citizen NPCs, such as using the same "Ugh!" sounds when both the NPCs and you take damage.

Your first-person playermodel is a Citizen's model, instead of HL2's normal HEV suit model, and regardless of your chosen Playermodel in Gmod.

I'm not sure if this is a glitch or intended, but as part of the new HUD, we don't get crosshairs. Normally i wouldn't mind it, but HL2, least without mods (yay for us that we're playing Gmod then, huh?) has no ironsight compatability, so freeaiming without any targeting support's annoying.
