What if everything that went wrong on "A Red Letter Day" was not caused by what you thought? What if your teleport ripped a hole in space and time? Now you must travel through time to correct the events and set right your past.

We need a special label or something for this idiot map makers who think hard = good and then they should be booted from polite company. This is as fun as a cavity. Stop making games mods or maps like this.

so, the game doesn't work quite right, it won't save, and the second map won't load on its own, not to mention that the third map loads with "ai_disable" set to 1, and i can't get it to change back, no matter how many times i put "ai_disable 0" in the console

It looks good, very nice. BUT, as has been pointed out already that first street battle has me dominated. I just can't get past it. Very frustrating indeed. I'm on medium difficulty and just get my *** beat no matter what I try. The Combine Gunship is the easiest kill of a Combine Gunship ever. Yet we get overwhelmed with too many Combine troops.

I don't want to cheat but not all of us are EXPERT FPS killers. I generally find Easy setting to be WAY too easy. Might have to go there anyway...

OK, so I figured out how to get past that first choke point. THEN you have to deal with that open area and multiple Striders and then multiple attack choppers! REALLY? Considering how weak most of the weapons are in HL2 that's just bloody ridiculous... Too bad because it's a beautiful mod.

I applied the patch to make the game actually run but it cant load the maps. Any help would be hot.

Toby, same thing happened to me on first try at installation, patch included. I then deleted the mod including the original download file. Redid everything a second time and it worked! Street battle still has me befuddled though!

Hello, i seem to have an issue when starting to play this mod. I get the error message "Can"t find background image materials/console/startup_loading.vtf", please help. I installed it correctly into the sourcemods folder, and have half life 2 installed.

it's easy to fix, just need to replace some lines in the file "gameinfo.txt"

every pre August 2010 mod has this issue, just google: Fixes for HL2 mods broken by the SteamPipe update.
