Adventure Awaits!

In typical retro-gaming fashion, Mystery Island II adopts a design similar to the classic game Myst! Mystery Island II is a port of our old HyperCard game so that it can be enjoyed on modern systems today.

Your name is Lt. Steven Bushell, and you are currently stationed aboard the USS Volarus, a US nuclear submarine.

While on a routine patrol of the Pacific Ocean, the USS Volarus is mysteriously destroyed! A Russian nuclear warship seems the most likely possibility. However, there were certain unusual aspects of the attack which left you wondering if that was a correct assumption afterall.

Enjoy Mystery Island II on either a Mac or PC!
Take yourself back in a time machine to 1990s gaming as you unlock the secrets of Mystery Island. No special effects. No voice acting. Raw, unadulterated, corny gameplay!
All of the music featured was composed and performed by Mark Sumner!

The Mission

You alone manage to escape the explosion of the submarine alive. After days of drifting in isolation amidst the vast ocean in nothing more than a life raft, you wash upon a tropical island. Your new mission: pin point your location and solve the mystery!

Game Soundtrack

Mark has taken incredible pride in creating, and updating, the Mystery Island soundtrack as the years have gone on.

Graphically simplistic but absolutely wonderful in terms of gameplay. I used to play these types of games a lot back in the day. Challenging and engaging. I completely recommend this to anyone that enjoys playing these types of adventure games.

Noah Richards

I love this game so much! I've played it for so many years, dating back to 2009, and enjoy every play through. Koingo has managed to capture a beautifully unique atmosphere in this game. The combination of the retro graphics of the brilliant alien environments and the outstanding classic synth soundtrack by Mark Sumner is a harmony so rarely achieved in games. I also cannot express how much I appreciate the fact that Koingo consistently updates this game to work on modern software as so few games do these days. 5 stars, cannot recommend enough if you love fantastic old sci-fi retro puzzle classics!

Augustus Hatt

The interface is really easy to use. Simple but effective. Just like the good ol' days of point-and-click adventures. Brings back memories, that's for sure.

Tony Miles

The game has an odd feeling of nostalgia to it even if you've never played it before. A real mind-boggler. It gets your creative juices flowing just trying to figure out how to advance to the next area. I really enjoy the challenge and recommend it to anyone else looking for a simple adventure game with some really good content.

Christopher Bates

Ahh, this game brings back memories. Point-and-clicks have been nothing short of a long coming hobby of mine and I was pretty stoked to add this one to my collection. A good challenge that definitely keeps you hanging on what's going to happen next!

Sherri Stewart

I love alien games! This one is pretty neat. Challenging and unique, it really gets you thinking and observing. Recommended to anyone that likes puzzles and is up for a good challenge.

Pete Walters

I expected this game to be easy. I was pleasantly surprised when I found that it offered a good, reasonable challenge. The graphics almost add to the creepy feel of it, too. Definitely worth checking out, even if you're not a huge gamer.

Don Graves

Great game. The graphics are old-school in the best way possible. They just take me right back to the old generation of Macintosh computers and how magical it was to play games on them back in the day. Brilliant.

Juanita Clarke

I love the genuine old-school foreboding feel that this game gives off. It almost creeps me out. They've got the post-apocalyptic feel going on and they convey it well. I recommend giving this game a go at least once, whether you're generally into these types of games or not. You might just be surprised.

Marion Hayes

Simple but complex! Don't judge this game by its cover (or in this case, graphics) because it's actually pretty good. You won't know until you give it a shot, though. It starts out a little slow but gets really good. I recommend that everyone try it at least once.
