AS:RD have reached rank 6 of 2000 games on Greenlight with 'Yes' Votes 5,131 (73% of total).

Thank to everyone who have took part in voting and spreading the word.
Huge thanks to those individuals who have donated us for the greenlight fee.

On 6 Jan our store page became public. You can now add it to your wishlist and click Follow button to show your support. This will help the game to get promoted. Also send the link to your friends and social media ;) The Install button doesn't work since the game is not yet released.


Feel free to invite your friends to our Official Steam Group

We also want to let everyone know that Alien Swarm: Reactive Drop will include significantly improved versions of Tears for Tarnor and Lana's Escape campaigns as official campaigns.

These are the two of the best user created campaigns for Alien Swarm. The original authors worked really hard to improve and balance maps since the last public release. We work on adding single-player support for these campaigns.

Below are some screenshots from these campaigns which can also be seen on our store page:

Hope it's Greenlit geotavros! Would love to see the the added items/weapons completed & refined along with more unique items and weapons added to the game. Could you add the jump boots and ...teleport?... items to the item selection menu? Could you make an item/s that enables stealth/camouflage until firing/moving and add a certain monster that can detect that ability & possibly stealth itself as well? It would go great with the sniper weapon.
People use the turret as a blockade in certain places, could you add an item that has multiple barrier charges that could act like a customizable wall? Smoke/flash bomb items that has a combination or single use of stun/poison/slow/conceals the area?

Eh... sorry overdid it... yes this is a solid game still worth playing friend me if you still play or want to play.

I can't play any maps in single player because the game doesn't launch them in the single player menu, I selected the map I wanted to play and kept on clicking the play button but it never takes me into the the game, I'm just stuck in the Chapter Selection menu :l

Nest campaign should be in place between "Biogen Corp" and "Area9800" when you create a game. Can you post a screenshots of your Greate Game menu with missing Nest campaign?
