I don’t know how long Amazon is doing this deal but my Toy Soldiers Steam port is in there and that would be cool if you wanted to buy it. It’s worth it to get Mark of the Ninja for ten bucks alone, but then you get all those other games too! All the keys are for Steam versions. So act.
Don’t forget that my friend Robert West’s Gnomoria game is almost a year old and contains a ton of new content. It was successfully Greenlit on Steam and he’s working on getting it to a 1.0 state to put it up there. So purchases now, through his site or Desura, will receive a Steam key later on when it’s up there. I hear you can get destroyed by a horde of invading mantis creatures.
Real update later in the day.
