Guns of Icarus Online is a steampunk airship combat game with a heavy focus on cooperation. In other words, you and your fellow teammates will each have to take on a certain role (Captain, Gunner, or Engineer), and then try to bring down enemy ships through a combination of teamwork, tactics, and trickery... or just fall out of the sky because your Engineer decided to take a coffee break.

If this sort of multiplayer madness sounds like something you would love to toy around with, you'll be glad to hear that Guns of Icarus Online is free to grab for the next two days. Simply head on over to the Humble Store, grab your Steam key, and you'll be playing in no time. If you need a bit more information, however, allow me to share with you the original launch trailer. Have a look:

While you're there you might also want to check out the currently ongoing Halloween Sale. You can grab games such as Amnesia, S.T.A.L.K.E.R., The Walking Dead adventure series, and much more at a very steep discount. So if you're looking to fill out your backlog, make sure to give the sale a glance. I would personally recommend the original Amnesia as its one of the rare few horror games I genuinely struggled to complete due to how stressed out it made me. Its not something I would always recommend, but since it is Halloween it might just be the type of experience you're looking for.
