Another slow day at work... been slow all week now... so you decided to go home early. But as soon as you start to leave, the combine start to break in. Entering the bosses office, you arm yourself with a pistol, and try to kill every combine you can, but they were coming in overwhelming numbers. You chose to get the hell out of there ASAP, only to be injured during the process and to find yourself hiding in a sewer.
You wake up, wondering what just happened. As you get up from a blood stained mattress, you find more of your friends already dead. Grabbing a crowbar, you work your way through the sewer to find help.
In The Sewer, you play the role of Malcolm, a rebel fighting for his life to get to safety.

is there new guns in this mod? or just the original from half life 2?
this mod is to l4d2 or hl2?
It's for HL2, I'm turning it into a Left 4 Dead 2 campaign now.
I have been waiting since all you had were hallway images, and now I don't have my computer and its released ._.
Man, I got two of the batteries, but the one you are supposed to get second, I can't find.
For your Information, that the Key to the Maintenance to get the 3rd battery is inside Bio Hazard Corner before you went up to get two battery.
That was one hell of a mod. Pretty long gameplay. The puzzles were ok except the lasertrap. Impossible without reading the walkthrough. ...maybe a little bit to many puzzles. The keys looked ugly, guess your are no modeler ;) (no offense)
All in all not to bad but some diversion. :)
Dude, I have no crosshair. Is this normal? Kind of hard to aim without ironsight. I have this error message in the console:
Hud element 'CMapOverview' doesn't have an entry 'overview' in scripts/HudLayout.res
Any suggestions? Thanky
edit: Just activated it with the console command: "crosshair 1"
Haha... Thank you. I thought I was the only one. I played up to a point without it.
