Half-Life: Sum

News 6 comments

Half-Life: Sum takes place during and after the resonance cascade in which you play as the tough as nails HECU grunt Jane Doe as she has to wade through 11 sprawling maps.

A compilation of my three previous mods, "HTC", "Autonomy Lost" and "Abeyance", into one large mod. Contains new stuff as well improvements into both the gameplay and level design based on feedback from the Half-Life community.

Half-Life: Sum


Even if you've played the previous mods I'd highly recommend playing through Half-Life: Sum just to see all the new additions and improvements.

I don't have a set release date but it'll be very soon. Keep an eye on the download section.

Personally I liked the red and blue Half-Life shipping containers more.

There is an unpleasant bug with the sound of walking, and so the mod is cool

What bug with walking sound? You mean assassins walking sounds? They are made this way in Half-Life.

And maybe I'm the only one with the problem, but the game starts to lag terribly when night vision is turned on

Hey man, I'd really like to play this, but every time I load in, it's incredibly laggy to the point that it's just flat-out unplayable. I've even deleted the game files and reinstalled them to no avail. Any idea on how to fix this issue?

Yes, it's only this one that gives me trouble. Trust me, I find it really strange as well.
