DEEP SIX

The years following the Armistice of World War I have left the world in a fragile but stable peace. Signals Corps engineer Alice Albright is on a special assignment investigating rogue signals at a foremost research airbase in the North Sea. Soon after her arrival, the base is attacked by a rogue militant group, cutting her off from escape and leaving her trapped on the island.
In an era that predates special forces, Alice is armed with nothing but her wits, a state-of-the-art wireless radio, and any other gear she can get her hands on. Secrets unravel around her as she attempts to infiltrate the hostile base, save her team, sabotage a sinister plot, and escape alive.
This is a lone sneaking mission. Weapons and gear will be OSP (on-site procurement), aid will come from anybody she can save, and failure could mean a second world war.
Layered Stealth:  Time of day, weather, sound, movement, and position all affect how easily the enemy will notice you. Break lights, sabotage equipment, and use the environment to create diversions.

You're in Control: Shoot, choke, distract, stab, slice, throw, sabotage, knockout, holdup, loot, drag, lure, tranquilize, or simply avoid enemies. Control Alice in your unique play style.

Radio Drama: Full voice acting for all characters in every cinematic and radio call. Call your team for tutorials and gear explanations, keeping you informed while maintaining immersion.

Low-Tech Stealth: Minimal tech, analog equipment, vintage and experimental weapons, all procured on-site. Day, evening, and night missions in clear, stormy, or snowy weather, across unique open maps. The way stealth was meant to be.

Old School Cool: Nostalgic 'PS2+' aesthetic, with modern lighting and texturing techniques, but optimized so you don't need the latest hardware to enjoy it. It's AAA if the year were 2004.
