Download Swarm Director 2 v2

Please note that there are no custom maps included with this version. I have decided to make Swarm Director 2 work as well as possible with pre-existing maps without redistributing them. A list of suggested addons and where to download them is included in the addons folder and is reproduced below:

If you have another favorite custom campaign, feel free to link it in the comments on this article.

Improved AI Director

All Director-spawnable aliens

All alien types seen here can be spawned by the new director, both as members of hordes and as wanderers around the map. The frequency of hordes and wanderers depends on the difficulty settings and the number of marines, and can also be tweaked by mappers.

The frequency of each individual wanderer type can be modified for each map - for example, Sewer Junction B5 has more parasites, mortarbugs, and harvesters than Landing Bay, and the first map of Paranoia has more boomers and shieldbugs.

The director can also spawn multiple NPCs together. This is currently used to spawn 4 shamans in a pack, but it can spawn any combination of alien types and scale health, size, and speed, or even make an alien immune to fire, ice, electricity, or flinching.

The AI director uses spawn lists based on Alien Swarm: Beyond Brutal with the new drone mutations added.


The asw_controls cvar is now per-player. This means that a group of friends no longer has to agree whether they want first or third person. Each player can choose separately. The game will also store your choice for this variable between sessions. There is no need to use the firstperson or thirdperson commands - the game handles it all for you.


Swarm Director 2 v2 contains fixes for several common campaign bugs which caused things like bad AI pathing, bot marines not following correctly, maps built for insane spawning not working on brutal, and so on.

It also fixes several map-specific bugs, such as events on Cargo Elevator and Oasis Colony Spaceport triggering without all marines present and mission failure being triggered if a tech died when he was no longer needed on the Dead City maps.

Additionally, Tears for Tarnor, Operation Cleansweep, Royal Harvest, and Zoidberg Reactor no longer attempt to load each others' credits, and Jacob's Rest no longer requires two marines for any of its missions.


func_asw_fade and prop_asw_fade have been added. These allow mappers to build things like ceilings and bridges that the player can pass under in third person but still see in first person. They fade to a mapper-specified transparency in third person when the active marine is below a point controlled by the mapper in Hammer. Faded func_asw_fade and prop_asw_fade are ignored by traces such as targeting for arcing weapons like the grenade launcher and flares.

...and more

  • Medic bots will now use heal beacons if the squad is missing a total of at least 90 health.
  • Several weapons aim much more reliably in first person view.
  • The shieldbug's autoaim target has been moved from the front of its head to the middle of its bubble.
  • The radial menu and the hack menus work correctly in first person view.
  • Empty medkits are no longer usable in energy weapons mode.
  • Hand grenades are no longer removed at 0 charges in energy weapons mode.
  • AI marines no longer fire their entire pistol clip at once.
  • AI marines can no longer walk on biomass.
  • AI marines no longer swap weapons when both weapons are out of ammo.
  • Improved positioning when avoiding boomer bombs, mortarbug bombs, and doors that are about to fall.
  • The experience bar during mission briefing now scales correctly for promotions 4, 5, and 6.
  • Drones no longer attack parasite eggs.
  • asw_egg entities with no angles are rotated randomly.
  • The keyvalues for asw_spawner from AS:SP and AS:RD are supported.
  • trigger_playermovement now works on marines.
  • asw_auto_record will save demos of missions you play.
  • Added asw_tilegen_instance.
  • Deathcam works in first person.
  • Spectators can see the minimap of the player they are spectating.
  • Marines no longer visually fall through moving floors like the ones in Operation Cleansweep: USC Medusa.
  • Optional motion blur has been added for aliens, marines, doors, and physics props.
  • Fixed loadout changes not checking which player owned the marine.

hmm.. if this is to be compared to UDK, then you would have to be able to make any kinds of games with the Alien Swarm SDK and not just mods for it.

so is this possible?

This game is soo fun. With the console commands i figured out from a steam news update, its even better. L4D-esque horde spawns add a little spice, especially when tweaked a little to specifications. It made soloing Landing bay on easy, well, not so easy :P but i actually made it through one >.^

1. Start a multiplayer server normally
2. Close it
3. Type "map lobby" in console
4. Type "sv_cheats 1" in console
5. Invite friends

The fact that this game is free continues to amaze me. Alien Swarm is a top down shooter that feels like futuristic Diablo II to a large degree. You fight off hordes of aliens with your friends in order to complete missions that require teamwork skill, and sometimes a little luck. The game has RPG elements – you level up and get access to new gear, there are four character classes, and multiple characters within those classes to select. This game should be a popular addition to any LAN party or…
