Alien Swarm Swarm Director 2 v.3.0

Description
Alien Swarm with a twist. Better AI, new mutations, new mapper tools.
Sadly, Alien Swarm was all but abandoned by Valve, with no updates to the core game since 2010, the year the game was released. But because it�s free and open to modding, anyone can continue from where Valve left off.
Although Swarm Director 2 improves gameplay on several official and custom maps, it does not contain its own content. Instead, a list of suggested custom campaigns and a place to download each is included with the mod, and fixes for bugs in those maps are written in C++ as part of the mod�s code. Additionally, if you have Reactive Drop installed, Swarm Director 2 will load the Extermination, Operation Cleansweep, and Paranoia campaigns from it.
We also add new features for mappers, the biggest example being a new pair of entities that can be used to make ceilings, bridges, or basically anything that would normally block your view in a top-down perspective but would make sense for someone looking through the eyes of a marine to see and for light to bounce off of.
How to install:
Extract into ��Steam\steamapps\sourcemod� and restart Steam client.
