About Hypovolemia with 4 comments by defragen1 on Jan 21st, 2014

Thank you everyone that helped us get Steam green lighted! I'm very pleased about that, despite somehow having more no votes than yes lol. No worries, with new illustrations being worked on, we will have a much better time promoting the game in the near future.

I have uploaded a new video! In the video, an updated version of skygrounds can be seen and the latest iteration of our flashy particle effects.

The SPK ( Russian faction ) will spawn with TWO item_vodkas instead of a single medkit ( which heals 50hp ).
Drinking each vodka will heal 25hp and we plan to make the character throw/smash the bottle into the ground when he is done drinking. As always, you can not have enough destruction! Also, we have way more gibbable models in the game now, so expect a good ol' smashing!

With that out of the way.. I would like to announce that I have begun pimping our HYP facebook page!
So please hop on over there and give us a like! Exclusive development pics and other goodies can be found there.
Hypovolemia Facebook Page!
I would like to see the community unified in someway before our upcoming/second release.
There's nothing more I would love to see than at least 1,000 likes on our Facebook before we unleash 0.2.

So hit us up and show your support, go go go!

Does anyone know if the difficulty sclaes correctly with the number of players? I was playing the campaign with my brother and we where forced into playing medic/technician in order to have sufficient utility, but we lacked having a balanced squad since AI players do not join, making the game very difficult even on normal.

Not really sure how you can list whiny kids saying it's a free game so it shouldn't deserve proper feedback. If anything I would expect the whiny kids to be the ones who would want to complain about stuff they don't like in a free game. So to be honest, I'll stick with, if you don't want it, don't download it, simple as that. also, thats not really a con of the game, thats just pointing out something you hate about the community, so therefore shouldn't really be on the list. I agree constructive criticism is fair enough.

I actually love this game, it's just too bad the campaign is so short. although, I can imagine people are already working on custom campaigns for it, much like left 4 dead.

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…
