Get Killing Floor for free right now
The Humble Store seems to be running their own Summer sale and, to celebrate, has marked down the first Killing Floor significantly. To be precise, it’s been marked down by 100%.
For the next two days, the Humble Store is giving away as many copies of Killing Floor as there are clicks. No strings attached, just free zombie killing goodness.
You can still donate if you would like, with 5% of the money being sent to Charity Water.
You can secure your copy here.
