Orphan of the Machine is an adventure game for current/next gen consoles and PC. The story takes place during the 60's - in the middle of (a fantasy take on) the Cold War. Russia, in their growing paranoia, begin developing cities underwater to hide from the threat of American espionage. Their construction disrupts sea life, and as the game begins, a baby dolphin wakes to find her entire family gone. What would you do if put in this situation? Where would you go? Instead of just placing markers on the map telling you exactly where to go, we let you explore and figure out what it is you want from the game. Do you believe your family is still alive? Could you find them? Could you seek out a new home? The game plays similar to a Metroidvania. The screen scrolls in all directions (in a 2.5D space) and there's a map to track your progress. You will need to collect certain items or abilities to get to new areas. As you grow and get deeper into the world, combat will become important to survive the most vicious of predators.
