if you right click on steam on killing floor they added the dlc menu,(no content yet) but hopefully we wont have to pay, because why not just include it in an update
To quote me from steam forums:
Somethings are in the works guys. We have a few patches lined up and on the way. Among these will include all of the usual goodies some of the RO players have come to expect of Tripwire (maps, and OTHER things, won't say what yet).
As to the DLC tab and why it is there now I'm sure there will be news on this shortly.
maybe the DLC is like a $10 addon SP campaign? you can play as one of the 6 ppl as you attempt to save england from the zombehs. sounds possible to me
You know what? If TWI wants to sell me some keen well-tested maps and new gameplay modes? I'm in. I want them to keep making stuff for my pleasure. Keeping them fed and living indoors does wonders for that.
