Sepolcro is an infection map I've been working on for a while now. Forged in the skybox, this multi-layered map will have you fighting for your life against the undead pouring in from all directions. Main body of church (incomplete) Crypt
Are those in-game effects..? That could severly damage gameplay, most people don't really like effects that are too intense in maps. The second picture looks interesting. I can't tell but it seems like a long dead-end hallway, which would promote camping.
The only effect on this map is "Gloomy", but I did edit the picture in photoshop. You can see the original pic here. As you can see by the original pic, it is well illuminated like the rest of the map so it shouldn't ruin gameplay. The second picture is a picture of the crypt on the map. On the right of the picture is a small doorway which is where people can enter from a staircase leading down from the church part. There is also a huge entrance from where the picture was taken (essentially a huge hole in the ground which zombies can drop down to get into the crypt). Zombies spawn inside those four caskets, and there is also another "secret entrance" So in essence, you could camp at the back on the left if you really wanted to but there are enough directions that you can be attacked from for you not to be able to watch all of them that would discourage it.
