Alien Swarm is a game which uses the Source SDK. Alien Swarm is a release from a group of talented designers at Valve who were hired from the Mod community. Its the sequel to Alien Breed: Impact, which was build using the unreal engine. Its a top down squad-based shooter where you can level your character and gain new guns and aditional items.




Now what is Alien Swarm exactly? Steam gives us the following description, which actually fits it perfectly:
- Tactical, 4 player co-op action game with a top-down perspective
- Complete game code and mod tools
- Unlock persistent items by gaining levels
- Over 40 weapons and equipment with countless loadout configurations
- 4 unique classes and 8 unique characters
- Matchmaking, Steam Cloud, Steam Stats
- 64 Steam achievements
- Tile-based map generation tool
- Powered by Source and Steam
The game consists of 4 different classes and 8 different characters (2 characters per class). Each class has it’s own special weapons and items. You can choose one of the following:

What are the requirements?
Operating System: Windows® 7 / Vista / Vista64 / XP
Processor: Pentium 4 3.0GHz
Memory: 1 GB for XP / 2GB for Vista
Graphics: DirectX 9 compatible video card with 128 MB, Shader model 2.0. ATI X800, NVidia 6600 or better
Hard Drive: At least 2.5 GB of free space
Sound: DirectX 9.0c compatible sound card
How do i get Alien Swarm?
Alien Swarm is free for now, and is provided by Valve through the Steam platform. This means you are going to have to get yourself a Steam account. You can get an account for free at steam’s website. Even easier is to directly download the steam client:
When you downloaded the steam client register for a free account and follow the steps below.
- Make sure you have the minimal system requirements
- Run the Steam client and login
- Go to http://store.steampowered.com/app/630/
- optional: Go to the steam library and search for: “Alien Swarm”
- Download the game, it’s about 2GB so how long this takes depends on your internet connection speed
- When the download has finished your Steam client should install the game itself and all you have to do is sit back and wait
- When the game is installed your good to go and you can get your game on!
- Tweak your settings if neccesary, see here.
Custom maps
At the moment you can only play one campaign, i admit its a nice campaign but it gets boring over time so thats why you can make custom maps yourself! or you can download them. We have collected a couple for you and you can download them from OrangeSwarm. When new releases are made we will post them here aswell so make sure you post a comment containing a link to the file when you find new nice custom maps!
THESE MAPS ARE OUTDATED.
However, when trying to play them a link to the latest version will be shown.
- Alien Swarm Custom map: Dash v2.5 (23.1 MiB, 600 hits) - Registration required.
- Alien Swarm Custom map: Infested Office (3.0 MiB, 481 hits) - Registration required.

- Alien Swarm Custom map: Survival Deep Freeze v1.0 (4.2 MiB, 392 hits) - Registration required.
- Alien Swarm Custom map: Naks Complex v0.1 (80.9 KiB, 326 hits) - Registration required.
How do i install those custom maps?
- optional: Extract the files from the rar file (a .VPK file should pop out)

- Start Alien Swarm and go to “Options” than “Add-ons” and activate the maps / mods

also these versions are not new at all, update the links damnit
here one http://forums.steampowered.com/forums/showthread.php?t=1371699
The office map is currently the latest version
when you download them it will tell you their outdated and they should provide a link to the latest version… we never said we would keep these files updated, we only provide them here as a early head on. besides that, we have 2 admin’s and 15000+ members which means its basically impossible for us to keep all articles updated.

This is the most inconsistent site I’ve ever seen. The title of the site is OrangeSwarm. The domain is SetupSwarm.com. This article is called Alien Swarm. It goes on to talk of ‘Alien Breed’. I suggest you learn to keep some consistency, and also fix your grammar and spelling.
THIS IS ORANGESWARM
basically we dont give a flying fuck
I figured that, I’m just saying it’s a crappy website.
Quick reply, +1 for you
I edited it now
And the domain issues.. yah.. long history filled w. ownage and legal issues..
You still haven’t fixed the grammar issues I spoke of, misspelling of necessary, improper capitalisation et cetera.
Are you applying for a moderator position?
This website isn’t that bad… it’s just nobody posts stuff, theres a new guide or info every 3-4 weeks.
Admins are drinking waaay to much to do useful things
btw anyone can submit an article

You could include a direct link to the Alien Swarm install instead of giving directions on how to search for it. steam://install/630 if I’m not mistaken.
