Iron Coffin

As the captain of a rugged diesel-powered submarine, you are tasked with a simple mission—deliver a mysterious package to a classified location deep beneath hostile waters. Nothing can go wrong. 

Except for the enemy submarines hunting you.
Except for the failing engines, leaking pipes, and flickering lights.
Except for the eerie sounds coming from the hull.
Except for the things lurking in the abyss, watching… waiting. 

With your vessel barely holding together, every decision is life or death. Will you fight your way through or sneak past unseen dangers? Will you patch up the sub or push it past its limits? The deeper you go, the less certain survival becomes. 

After all, nothing can go wrong… right?
