Shad'O is more than a simple tower defense game.
It's an experience that transports you into a world of dreams and memories.
And it was important for us to construct that "Alice in worderland" universe around the storyline.

Because you will discover the story backward! You start from the end of the story and have to,step by step, remember older memories to understand what's going on, where everything started.

The tower defense is a good game type for defending the memories of the boy.

But we wanted something more, something that makes the shadows more "viral".

So we created the "Fog" of oblivion.

That procedural and living fog, that covers every memories in the game, brings a new way to approch the tower defense game mechanics.

We think the mix between that dreamlike world, the story, the fog and the freedom of game tactics make Shad'O a very appealing game.
