EDIT: The DLC which lets you play it in vr can't be made 100% off, so the devs are pricing it at 60c NZD as that's the minimum steam will let them.
The base game is free to keep, by the way.
Put in a request for a free key for this a bit ago, but they ran out of keys and sent this email:
Sorry for the delay in getting this email to you. We received a huge amount of demand for access to our free Four Kings giveaway, which has left us short on giveaway keys, and frankly a little overwhelmed!
But we didn't want to let you down. So, we've worked closely with Steam, to be able to provide the game via their platform for free for three days only. No special codes required!
To get your hands on Four Kings One Warâ„¢, simply click on the link to Steam below - where you'll get free access the full versions of both our PC/Mac or VR game, available for 72 hours from 1am this Saturday, 16 May (Pacific Standard Time).
1am PST 16 May, you'll be able to get the game in vr or non-vr mode to keep.
Got the same email.
