enelin8 is a sci-fi 3d shooter. You receive a cryptic distress call from the moon Beya B4, normally inhabited only by robotic mining drones. Upon setting out to investigate, the drones attack you. Blast your way through walls and defenses with your well-armed shuttle, deeper down into the robotic mining facility towards the source of the distress signal.
enemy lines 7 is a game that is a bit experimental. You are a damaged alien spy probe. With visual systems malfunctioning, all you have left for navigation is a particle detector. You have to reach your pickup zone before system failure. Basically, you have to navigate through a 3d environment in first person view while the only thing you see are a few dots of the walls here and there.
