SAS3 was a long time in the making. We had so many people email and ask that we make SAS2 into a multiplayer game, and eventually we agreed it would rock if we did it. However it was easier to just completely remake the game as a sequel than to retrofit into SAS2. In the end it took way more time and effort than we ever thought.
Here it is finally for those who haven't already been playing it on ninjakiwi.com.
You can play single player or multiplayer, in either mode you get experience and rank up and unlock new stuff.
We have loads of updates planned, new guns, maps, game modes etc.
