I’ve played it a few times over the years but not in a while. I don’t remember if the Lost Vikings 2 was also a DOS game or was released for Windows, but it had some new characters with special powers.
I played quite far into this. I’m not sure if I ever finished it though. It’s one of those games that seems to go on maybe 1/4 longer than it needs to, and I remember losing a lot of motivation by the last world.
