This is de_piranesi from Counter-Strike: Source, ported to l4d2 by me. Unlike other css survivals this map has 4 Counter-Strike weapons.

Thanks to
- Urpoliitikko for beta testing
- Mewlava for making map poster

Note: Css weapons doesn't do damage unless you play on local and after first time call a vote "return to lobby" and start game again. However map is playable without css weapons.

A trip through the underground of a city to reach a train station for evacuation.
This campaign is base on the industrial side of Philadelphia, with the original survivors.
There are few optional crescendos in the campaign including light generators. Either play in the dark or light your way, with a small penalty of a crescendo.

A campaign that is a sequel to Never Ending War. I have been working on this campaign for a good long while along with 2 other short campaigns.

The survivors get kicked out of Nick Smith's car (then it crashes) and they have to go on their own for a while to a subway and then to a pier.

Hashima island, commonly known as "Gunkanjima" (meaning Battleship Island) is an abandoned mining town located on an island West of Japan. Years of harsh weather conditions have turned the island into an urban ruin.

Features a weather cycle: Every 5 minutes, the sky darkens and rain starts pouring. JimOnions created this beautiful TTT map, which I ported to L4D2 survival. Thanks to K1CHWA, Nicadeamus and Bloue for their help, and a big thanks to Soul for the tons of work he put into optimization and gameplay balance!

IMPORTANT
This map requires my particles mod (linked below) to function as intended.

Inspired by Kylemore Gothic Church and Rotenberg mausoleum. Map is still under construction and beta status.

A 5-map campaign set in various locations throughout Japan. Survivors start in Tokyo's red light district, escaping to Kyoto's Kiyomizu temple, before moving further into the mountains the next morning.

Includes versus mode, which works but wasn't tested much as it was only included as a bonus. Also includes survival mode in 3 of the 5 maps.

You must battle for survival within the walls of the legendary Lumbridge Castle.
This map is as close to a scale replication I could make. Obviously there had to be some balancing changes to make the map in a zombie apocalypse somewhat enjoyable, such as the cellar escape hatch outside.

If you find any bugs/glitches in the map, please explain in detail. Thanks and enjoy.
