While all the world is looking at Steam Summer Sale, which is accompanied by overloaded servers, Humble Bundle offers a horror classic for free. The Killing Floor (2009) first-person shooter from Tripwire Interactive is free for two days.
The game has to be “bought” on the shop side on Humble Bundle in a classic way – in the shopping cart then 0,00 Euro instead of 17,99 € as purchase price. The offer will end on 24 June 2017 at 7 pm. At Steam there is the title in Summer Sale at the reduced purchase price of 4.49 euros.
