Huge thanks to those individuals who have donated us for the greenlight fee.

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:

for a free game, this is one incredibly fun sci-fi creation, building on steam's co-op capabilities, which gives it immersive replay value, making it an awesome return-back platform for general cooperative-skills practice with new gamers and relaxing eye-hand coordination training gamers usually seek. given its free access to the game's sdk, enriches the experience even further, adding various creative production of new game content based on valve's source engine. what would u need more from a top-down…
