Art wise this could be possible with alot of work & slight changes to the maps.

But gameplay/scripting wise i'd deem this impossible, unless you rework each level to fit Contagions gameplay/capabilities.

Better make original content in that case.

Yeah well, Barlowe isn't as big as a L4D campaign, and that was pushing it to the limit, the devs said, so i guess not :C

If not the whole compaign, but how about porting survival versions? Or taking one or two L4D compaign maps (instead of ALL compaign maps) and merge them into one big escape one? This might work. It‘s just like porting ZPS maps with exception for that fact ZPS maps not so massive as any L4D ones.

I was actually going to post in my previous one that to have a "start", port The Lighthouse survival level from L4D1.

That could work! How about the 4th and 5th level of No Mercy? And have the beginning of the map be when at the end of the 3rd level, the survivors spawn on the manhole they came from to the Hospital.

http://i.imgur.com/TCJIozr.jpg I took that long ago back when i first played Left 4 Dead, at the bottom of the picture you can see there's a small opening, it's the manhole from which you get to the hospital, to the right of the police car, if it wasn't off screen, the Hospital would be right there. Just show the manhole closed for the level not having to render a part of the sewer, then the first message the survivors get is something like "Man, what a stench! Am i glad we're out of there. Let's enter the hospital, the radio on the roof should get us out." to say that they were below on the sewer.

The Lighthouse for Flatline? This could be interesting.

I also was thinking about porting piece of No Mercy as a small demo of what can be done, but instead of that use all world brushwork and geometry of the first bsp file of No Mercy from L4D2 and content from Contagion (models, textures, sounds, scripting, triggers etc). Your idea sounds much better for an actual escape map than simple “demo map“ that I was thinking of, but anyway both ideas would require a lot of effort.

I'm against porting stuff but I'm curious if anyone has ported a whole official map from a totally different game yet. (Not between Valve games or Garry's mod)

I can't think of any so far, only some fanmade stuff maybe (Mario, Lego, Minecraft)

I've been working on doing the same thing with the skyscraper part of my custom L4D2 campaign. Stitching the maps together should be doable, but it's going to be a whole lot of work, and it's gonna need a lot of optimization tricks.

The original L4D comes with the source files to No Mercy. I think they're pretty outdated, but still better than the mess that is decompiling.

Rectus! Ever since seeing your Hunted version of the map in the Workshop, i was wondering if you'd ever make it an Escape one. Thanks a lot ^^

You mean porting (Taking it entirely, copy pasting it) or making it a block by block recreation?

I mean porting. Block by block recreation is a remake. Still, porting maps is not like porting models. A lot of work is involved and it takes time and additional work if you want to do it right.

Would like to see "Secret Lab" ported to left 4 dead 2 (supposed to be after the Bridge scenario)
