The official North American Shadowgrounds Survivor demo features two campaign levels and a single Survivor mode level.

First Level: Wake Up Call
The introductory level of the game has you playing as the Marine stranded on the outskirts of the colony New Atlantis. All of the Marine’s weapons are at your disposal as you fight to get back to the colony.

Second Level: Road to Atlantis
While searching for colony survivors, players will have to battle through hordes of enemy aliens. Save as many colonists as you can, but remember that survival is only half the game.

In Survivor mode you have the Spider Trouble level.
Play as the flamethrower-toting Napalm, as you try to hold out against a relentless wave of eight-legged enemies.

All weapons and upgrades are available for each playable character.
