Just like Zubon, I’m a little Tower Defense crazy.

Left 4 Dead strikes me as ripe for a Tower Defense mod. It already revolves around defending as gameplay, plus it has waves and waves of not-so-mindless zombies ready to go. The AI director could probably be tweaked for it nicely. If I had the coding skills (or at least more familiar with the SDK), I’d start a mod project, but I don’t so here it is as a suggestion.

It doesn’t have to be Towers, just auto-targetting / auto-killing devices of some sort. I’m imagining all sorts of devilish traps that could be placed in some of the narrow corridors and hallways typical for Left 4 Dead maps. Maybe movable barriers too, so the pathing of the zombies could be altered. Then the glorious gibbing of zombies would abound!

This could end up a little more like Dungeon Keeper than Tower Defense, but that’s great, since I’d count Dungeon Keeper as the epitome of build-and-turtle defense games.
